Abstract: Abstract Current progress of Computational Fluid Dynamics(CFD) researches proceeded in our laboratory (Mathematical Modeling and Computation), is presented in this article. In our labo., mainly three projects are running. First one is the project: Numerical Turbine(NT Project). A parallel computational code which can simulate two- and three-dimensional multistage stator-rotor cascade flows in gas and steam turbines is being developed in this project with the development of pre- and post-processing softwares. This code can calculate not only those air flows, but also those flows of moist air and of wet steam. Second one is the project: Supercritical-Fluids Simulator(SFS Project). A computational code for simulating flows of arbitrary substance in arbitrary conditions, such in gas, liquid, and supercritical states is being developed. Third one is the project for making a custom computing machine optimized for CFD. A systric computational-memory architecture for high-performance CFD solvers is designed on a FPGA board. In this article, the NT and SFS projects are briefly introduced and some typical calculated results are shown as visualized figures.
