Abstract: Abstract This paper describes outline and numerical results of a three-dimensional compressible flow analysis code, MIFS. MIFS is a multi-block BFC general-purpose code that can solve flows in complicated geometries. The complicated flow field is divided into small blocks that have rather simpler geometries and are easy to generate structured boundary-fitted-coordinate system grids. It employs a generalized equation of state so as to solve a wide range of hydrodynamic problems, such as the super-cavitation problems as well as the usual aerodynamic problems in the same solving procedure. The generalized equation of state consists of the ideal gas equation for gas-phase and a Tammann type equation for liquid-phase. These two equations of state are combined by a physical parameter, the mass ratio of gas. Numerical examples presented here are qualification test results. The results of the standard test of transonic flow past ONERA M6 wing and collapse of single bubble demonstrate MIFS can accurately solve these problems. The parallel computing tests results show the code has excellent parallel efficiency.
