In our laboratory, numerical simulations and computational predictions on engineering problems concerned with fluid dynamics have been carried out.
At the present day, computational fluid dynamics (CFD) is widely used for various fields. The fundamental one has been used to investigate the various phenomena in turbulent flows, combustion, multiple-phase flows and so on, while the practical one has been applied to design problems such as turbomachines, airplanes, automobiles, ships and atomic furnaces. However, the present numerical techniques have a lot of defects which lead unrealistic solutions or degenerate the degree of accuracy in certain cases. Especially, turbulent flows which are very important in engineering applications play a key role in this context. Because no universal turbulence model has been proposed yet, in spite of the necessity of introducing a turbulence model that represent turbulence effects approximately. Considering the situation described above, we proceed with the investigations on the highly accurate and efficient computation of turbulent flows by proposing a new turbulence model, modifying existing models and applying them to various engineering problems.
Every year about 12 undergraduate students and 8 graduate students belongs to our laboratory and each student tackles a different theme.
