    The research was conducted to understand the multi-scale transport phenomena in the polymer electrolyte fuel cells. The research revealed that hydrophilic carbon-fiber MPL (micro porous layer) gives better water transport ability than the conventional type, resulting in better cell performance and cold-start capability. The carbon type called “Vulcan”, which has more condensed inside-structure than the conventional one, has an ability to increase oxygen transport rate at the surface of the Pt catalyst. Additionally, the cell performance appears to be improved by the optimum control of side-chain structure of ionomers and their distribution in the catalyst layer. The Graphene, which has a structure of mono-layer of carbon atoms, may have possibility of greatly-reducing Pt amount for the same cell performance. The research also shows the optimum grid structure of gas diffusion layers by the developed scale-model experiment and Lattice Boltzmann Simulation.

    This research investigates a relation between the scalar conservation equation and the level-set equation based on local interface speed model for a premixed combustion flame. A new model formulation is introduced for the source term of the conservation equation in three-dimensional interface phenomena, which gives the solution of the level-set equation coupled with a re-initialization procedure for the physical interface problems governed by conservation law. It may be an extensional formulation for a diffusive solution of the level-set equation.

    To achieve the practical use of nonhazardous small rockets, We have developed CAMUI type hybrid rockets. CAMUI rockets are free from explosives and liquid fuels, resulting in lower costs for safety management. This research clarifies scale effects on fuel regression characteristics mainly by static firing tests. The firing tests covers Reynolds number range from a few thousands to over a half million. A numerical simulation clarified the mechanism responsible for the effect. By using these results, we can obtain basic design data by static firing tests of a subscale motor. Finally, we developed a 15 kN thrust class motor. Firing tests by this motor show good results, verifying the method developed in this research.

  • Study on Numerical Instability and Accuracy of Large Eddy Simulation for Complex Turbulent Flows
    Grants-in-Aid for Scientific Research
    2001 - 2002
    TANIGUCHI Nobuyuki; OSHIMA Marie
    Large Eddy Simulation (LES) is investigated as a generally accurate method for the complex turbulent flows where the statistical models are difficult to apply. However, LES was still difficult to perform accurately and effectively enough in the application to engineering problems. Here it is important to develop both appropriate numerical method and turbulence model to perform the LES in accurate and stable computation. This research investigated these numerical method for LES in the following points ; i) Numerical formulation of dynamic SGS model and its validation, ii) validation of SGS models in the micro-scale structure analysis using the numerical results by direct simulation, iii) study on the influence of inlet fluctuate condition and its validation in the annular jet flows, iv) proposal of numerical model for suppressing instability of LES and its validation in separated turbulent flows. These analysis and proposals were introduced into practical simulations of complex turbulent flows such as spray combustion, lift-up barrner flame and gasturbine combustor flows. Pulsating flow simulation in brain artery was also analyzed the above technique.

    This research aimed a development of large eddy simulation (LES) for turbulent combustion flows for the advanced design of combustors of energy plants or gas turbines. Based on the flamelet assumption which was developed in time-averaged turbulence modeling, LES methods and their subgrid scale (SGS) model are developed for various types of turbulence flames and the combined combustion flows. A dynamic SGS model is introduced into the turbulent flame models. As practical applications, prediction method for NO production in turbulent flames and combustion model of spray fuels are investigated based on the above LES modeling. For the practical LES of combustion flows, turbulence models and their numerical methods are developed based on the finite difference and finite element for the complex geometry. Some new results are reported with proposals of non-equilibrium SGS model for scalar transport, wall boundary layer approximation combined with the time-average turbulence models and numerical treatment of inlet velocity fluctuations in jet flows. Since very few cases were reported on instantaneous structures and unsteady scalar transport phenomena in turbulence combustion flows, advanced visualization methods are developed and applied to the basic burner flows. Dynamics and interaction of small scale eddy structures are also investigated using the database of direct numerical simulation. A computer code based on the above researches is probed on the practical problems, as NO prediction in diffusion flame, lift-up flame of combustion burner flow prediction in diesel engine cylinder, and premixed flame propagation in multi-stage combustor of advanced gas turbine.

  • Development and evaluation of numerical method for large eddy simulation of multiphase turbulence flows
    Grants-in-Aid for Scientific Research

    KOBAYASHI Toshio; TAKAGI Shu; OSHIMA Mari; SAGA Tetsuo; TANIGUCHI Nobuyuki
    An aim of this research was to develop models for a large eddy simulation (LES) of multiphase turbulence flow with dispersed particles and to evaluate and optimize them using numerical simulation. For modeling of multiphase flows, a direct numerical simulation (DNS) of bubble motions evaluated their effects on the fluid flow and the interaction between bubbles. Turbulence variation by small solid particles was also investigated. For evaluating a formulation of particle motions in the LES, a Lagrangian equation and a statistical averaged equation were compared by the numerical examinations. The numerical method of LES was developed based on the former model. These results were validated in views of the particles and the fluid flows using data of DNS and experiment with visualization techniques. For some basic flows, as mixing layers, jets, channel flows, the above models and the methods were examined in the range from laminar to turbulence, to indicate an universal information for the bubbly flow and the particle-laden air flow as follows,
    a) Particle size effects on the bubble motions by the buoyancy forces and the turbulence could be analyzed by the LES including the precise model of the bubble motion and its contribution to the volume averaged equation.
    b) The turbulence dissipation by the solid dispersed particles could be evaluated by a subgrid-scale model including the particle-fluid interaction, while a grid-scale interaction was not simulated by the present model effectively enough.
    These results validated the feasibility of LES to the dispersed-particle multiphase flows and indicated that the temporal and the spatial scales of the turbulence and the particle motion should be considered for the modeling of the particle-fluid interaction and its optimization.

    An aim of this project was to build a database for turbulent researches by using a large eddy simulation (LES) in a high accuracy approxmation with the latest turbulence models and numerical methods. The database was expected to include both the statistical variable data and the structural characteristics of turbulent flows.
    For developing the numerical methods and the subgrid scale (SGS) models for the large eddy simulation of various turbulent flows, some verification data were indicated for the latest proposed SGS models, a) a dynamic SGS model in the FDM and FEM formulation, b) a non-equilibrium SGS model proposed by Yoshizawa. According to these results, numerical programs were developed and improved to analyze the LES for seven objects ; 1) circular pipe flows with/with-out swirl, 2) a plane turbulent jet, 3) a wall impinging jet, 4) a channel flow with a cubic turbulent generator, 5) a flow around square cylinder and 6) a ventilation in the room with thermal stratified layr. Each object is researched with a physical or a numerical interest, a validation of LES by a boundary fitted coordinate (BFC) grid for case (1), development of numerical methods for boundary conditions for case (2), validations of SGS models for cases (3), (4) and (5), estimations of the affects by upwind schemes for convection terms for cases (4) and (5). For all cases, profiles of mean velocities, turbulent intensities and likes as statistical quantities are stored in the database of LES.Additionally, more detail data like a budget of turbulent energy compared with experimental data for the wall impinging jet (case (3)) and phase averaged quantities for the quasi-periodic turbulent flow (case (5)) were calculated. For analyzing the structural characteristics of these flows, two-and three-dimensional visualization were offered by the computer graphics and some by the animation, too.

  • DIRECT SIMULATION AND LARGE EDDY SIMULATION OF UNSTEADY FLOW INCLUDING SEPERATION,VORTEX MOTION AND TURBULENCE

    A purpose of this co-labolation research was to establish an accurate and effective method for the numerical simultion of unsteady flows with seperation and vortexes, esppecially using a direct numerical simulation (DNS) and a large eddy simulation (LES) of turbulence. For this purpose high-order accuracy schemes and boundary conditions were developed in the mathematical view and LES turbulence models were also examined from an physical analysis of turbulence structures.
    The above reseach had been performed in numerical methods of the compressible flow, high order accurate schemes and their application to the direct turbulence simulation by Chinese researchers, and also in numerical methods of the incompressible flows, boundary condition and their application to the large eddy simulation by Japanese researchers. This co-laboration promoted a development of more accurate and effective research in turbulence phenomena by an interaction between the both sides.
    The unsteady flows with the seperations and votexes are popular in the engineering, but have not been predicted correctly enough by a widely used Reynolds averaging model. The LES is expected to be applied generally and accurately to verious types of flows because it simulates a large scale part of turbulence motion directily. However, several problems should be researched before it is applied to the engineering : in mathematical view, 1) effective algorithms for the time marching analysis, 2) reducing numerical errors caused from the boundary conditions, 3) avoiding instability in the high order accuracy schemes, 4) boundary fitting method to the comlicated geometry, and also in the physical analysis, 5) development and validation of the LES turbulence models, 6) analysis of turbulence structures by the visualized data. Finally a large scale computation for the LES and DNS can be performed accurately and effectively enough.
    In 1995 budget year these researches were proceeded as fillows :
    Chinese researches investigated in
    a) development of stable and high order schemes with compact formulation,
    b) direct numarical simulation of the compressible turbulent shear flow. Japanese researchers investigated in
    c) instability and accuracy of the unsteady boundary conditions,
    d) development of dynamic models for the LES,
    e) large eddy simulations using the boundary fitted and unstructured grids, and also joint researches are performed in
    f) analysis of the visualization of the compressible shear flows by the DNS.
    g) applying the high order schemes to the incompressible flow simulations.
    This co-laboration has been proceeded by exchanging information constantly through an internet and also by visiting each other for discussing more detail. A part of this co-laboration results has been presented in an international symposium and will be published in an international journal coauthorized by the researchers from both Chinese and japanese side. This research program will be continued and extended to wider application of the DNS and LES to both the compressible and the incompressible turbulent flows.

    A spatial simultaneous measurement method for temperature and velocity of a complex thermal flow has been developed. The new method was based on the liquid crystal thermometry, the digital color image processing technique and the three-dimensional particle imaging velocimetry by the stereo photogramtry. This method was called the three-dimensional Particle Imaging Thermometry and Velocimetry (3D-PITV) . The conclusions of this research work can be summarized as follows.
    (1) The bragg-type scattering phenomenon of the micro-capsulated liquid crystal has been proved quantitatively through a digital color image processing.
    (2) The optical characteristics of color to temperature of the micro-capsulated liquid crystal is identified quantitatively by the neural network.
    (3) The response time of the liquid crystal particle itself has been calculated through a numerical simulation and its availability has been verfied with the possibility of the micro capsulated liquid crystal particle being used as a temperature sensor for the measurement of thermal turbulent flow.
    (4) The hardware system of the 3D-PITV which consists of a monochrome CCD camera, a three planes of color CCD camera, optical video disk recorders, a color image processor and a micro-computer has been constructed.
    (5) After confirming no effects of the bragg-type scattering, the system has been applied to measure a vertical buoyant jet. The radial distribution of vertical velocity and mean temperature show similarity with other researcher's results by one point measurements in self-preservation region of the jet.
