Research Subjects

  • Numerical Flow Simulation

    We are developing numerical scheme for analyzing incompressible unsteady viscous flow field. Engineering work stations under tight network are the main tool for the study. The FEM (Finite element method) and the FDM (Finite difference method) are both the object of the research in our lab. The themes range from natural convection problem to the flow around a wiper blade for automobiles. Evaluation of the mesh generation is also the theme.

  • Numerical Simulation of Road Tunnel Ventilation

    Road tunnels are equipped with forced ventilaton system in order to dilute pollutants such as soot or carbon monoxide, when the tunnel length and the traffic exceeds certain level. In the longitudinal tunnels, which are most frequent recent years in Japan, ventilation control is a problem, because the ventilation performance is strongly influenced by the traffic as well as meteorological conditions, etc. Therefore it is required to develop control systems with high performance. We are working on developing ventilation simulation system, solving the one dimensional convection diffusion equation, with which control algorithms and its evaluation methods can be tested in high reliability.

  • Automatic Measurement of the Flowfield

    We are developing the automated measurement system in terms of multi-holed pitot tube, or multi-wired hot wire anemometer. The measured data are transmitted to a PC and processed to caclulate velocity vector in high accuracy.

  • Utilization of Natural Energy

    Natural energy resouces such as wind or tidal wave are beging studied, and the machinery are being reserached and developed in order to extract the energy in higher efficiency.

  • Experimental and Numerical Anasysis of Wing Performance

    A lot of data are published on the performance of the wing section from NACA/NASA etc. However, the data are not available for specific wing sections of in low Reynolds numbers. Our study is aimed at such wing section performance by experimental and numerical approach.
