| Abstract: This paper describes present status of weather prediction and climate simulation using a numerical and future direction of its development. Numerical Weather Prediction(NWP) is one of the first trial to solve a fluid dynamics with thermodynamics. Its development is always accompanied with development of a high-end computer system. Global warming issues, which appeared in the late 20 century, accelerate the advance of climate simulation using a climate model. Information given by these models is being applied to various areas in the real society and considered to be crucial to future development of our society. | ||

| Abstract: The Navier-Stokes-Fourier equations have had a profound impact in engineering and are able to provide an accurate description of a diverse range of fluid flows. However, under certain conditions, this set of nonlinear equations is not suitable and will fail to predict observed phenomena. In particular, re-entry aerodynamics and high Mach number flows have regions where non-equilibrium physics is a critical factor. For these types of flow, applying the Navier-Stokes-Fourier equations will produce inaccurate results, such as shocks that are too thin. With advances in technology, we now find that the Navier-Stokes-Fourier equations provide a poor prediction of low-speed gaseous flows, typically found in micro-systems. As the length scale decreases, the conventional description of gaseous transport breaks down due to the flow losing thermodynamic equilibrium. This paper will look at recent progress in modeling this difficult and challenging fluid dynamic regime. In particular, we highlight how we have developed the Method of Moments as an extended thermodynamic set of equations and demonstrate that they can capture important non-equilibrium flow physics. We demonstrate their capability by simulating the flow induced by thermal stress between two non-concentric circular cylinders. | ||

| Abstract: Numerical studies on the heat transfer and flow characteristics of natural convection in an enclosure have been conducted by many researchers in a wide range of conditions for decades. Recently, the heat transfer and flow phenomena around the bluff body surrounded by the rectangular enclosure have been investigated intensively. The important factor for the change of heat and flow characteristics is the Rayleigh number, which is one of the important dimensionless parameter in natural convection, as well as the conductivity and location of the bluff body in the enclosure. In this paper, the heat transfer and fluid flow phenomena of natural convection in an enclosure with square shape body is shown at first, and then the results for the natural convection phenomena in an enclosure with circular shape body which is located at different locations in the enclosure is analyzed. Finally, the results of the three dimensional numerical study on the natural convection in an enclosure with a cubic and sphere body are presented. | ||

| Abstract: According to numerical methods the multiscale problems in the thermal and fluid science are classified into two categories: multiscale process and multiscale system. For the former processes at different length scales have different governing equations while for the later the governing equation is the same. The numerical approaches for multiscale processes have two categories: one is the usage of a general governing equation and solving the entire flow field involving a variation of several orders in characteristic geometric scale. The other is the so-called "solving regionally and coupling at the interfaces". In this approach the processes at different length level is simulated by different numerical methods and then information is exchanged at the interfaces between different regions. The key point is the establishment of the reconstruction operator, which transforms the data of few variables of macroscopic computation to large amount of variables of microscale or mesoscale simulation. For the numerical simulation of multiscale system top-to-down or down-to-top multilevel solution method may be used.Some numerical examples of multiscale simulation are presented. Finally some conclusions are withdrawn. | ||

| Abstract: Under continuing policies of the mitigation of GHG (Green House Gases) emission, it is crucial to consider scenarios for Japan to realize a safe and clean future electricity system after the Fukushima nuclear accident. The development plans of nuclear power and renewable energy - mainly PV and wind power - need to be reconsidered. Therefore, in the present study, three electricity supply scenarios in 2030 are proposed according to different future nuclear power development strategies: (1) negative nuclear power; (2) conservative nuclear power; and (3) active pursuit of nuclear power. On the other side, three electricity demand scenarios are also proposed considering energy saving. The purpose of the study is to propose electricity supply systems with maximum renewable energy penetration under different nuclear power development strategies and demand situations through scenario analysis. The scenario analysis is conducted using an input-output hour-by-hour simulation model subject to constraints from technological, economic and environmental perspectives. The obtained installed capacity mix, power generation mix and CO2 emissions of the scenarios were compared and analyzed with each other and with historical data. The results show that (1) penetration level of renewable energy is subject to the share of nuclear power as base load; (2) it is very difficult to remove nuclear power absolutely from the electricity system even when a high level of penetration of renewable energy is realized; (3) high level penetration of renewable energy can reduce the dependence on nuclear and thermal power, but there is a need for more flexible power sources to absorb fluctuations; (4) CO2 emissions reduction compared to 1990 levels can be readily achieved with the help of renewable energy, nuclear power and energy saving in 2030. | ||

| Abstract: Increasing demand for higher performance of gas turbines requires extremely high efficiency of a turbine blade cooling system. For further improvement in the cooling performance, it is necessary to introduce new technology to optimize the cooling system. Film-cooling have played important role in cooling high-pressure turbine blades, and the shape of film-cooling is most influential factor on the film-cooling effectiveness. Therefore, the surrogate based optimization techniques involving single- and multi-objective techniques have been used for film-cooling hole designs coupled with Reynolds-averaged Navier-Stokes analysis. The present article reviews the surrogate optimization techniques recently used in film-cooling shape optimizations. | ||

| Abstract: The motion of inertial particles in wall-bounded turbulence is investigated by using direct numerical simulations of vertical turbulent channel flows. In this study, particles are treated as point-sources. We mainly focus on the acceleration statistics of the fluid seen by particles to discuss preferential concentration of particles. The effects of lift and gravity on particle acceleration statistics are also examined. | ||

| Abstract: The non-equilibrium molecular dynamics simulation (NEMD) can be applicable to the transient observation of the local non-equilibrium state to the equilibrium state or the local non-equilibrium state itself at the molecular scale precisions that are significant for the numerical evaluation of the influence of the nanostructure geometry on the interfacial thermal resistance as well as that of the wet cleaning process of a semiconductor wafer. In the present study the NEMD were conducted in order to obtain various information about the local non-equilibrium phenomena of the liquid molecules in-between nanometer structures at the liquid-solid interfaces such as the influences of the nanostructure clearances on the thermal resistances and the liquid molecular non-equilibrium behaviors and the prediction of the wetting phenomena in the nanometer slit pores. The simulation results showed the pregnant information concerning with the interfacial thermal resistances and the transient wetting processes as well as new findings in the local non-equilibrium thermodynamics. | ||

| Abstract: Proper orthogonal decomposition (POD) method and its application in thermal science and engineering are discussed in this paper. First, the accuracies of linear and cubic B-spline interpolation POD methods are compared. Second, a comparative study is carried out to investigate the performance of POD interpolation and POD Galerkin projection methods for steady heat transfer problems. Then POD is employed to study the mechanism of turbulent drag reduction and heat transfer. Finally, the soil temperatures in a heating crude oil pipeline system are fast predicted by the POD method. The results show that POD is a good tool for the analyses of thermal science and engineering problems. | ||

| Abstract: This keynote reviews a three-dimensional steady-state model for modeling two-phase mass transport in direct methanol fuel cells (DMFC). The model is formulated by integrating five sub-models, including a modified drift-flux model for the anode flow field, a two-phase mass transport model for the porous anode, a single-phase model for the polymer electrolyte membrane, a two-phase mass transport model for the porous cathode, and a homogeneous mist-flow model for the cathode flow field. The two-phase mass transport models take account the effect of non-equilibrium evaporation/condensation at the gas-liquid interface. The computational results based on the model are shown in reasonable agreement with the polarization curves measured in a single DMFC that discharged with different methanol concentrations. | ||
