An efficient numerical simulator for calculating the unsteady transonic cascade flows and for visualizing these numerical data is developed. The authors have already developed a numerical method, in which an implicit time-marching finite-difference scheme for solving the unsteady Euler and Navier-Stokes equations in general curvilinear coordinates and several numerical techniques have been applied in order to simulate the unsteady flows having shocks and their induced boundary layer separations such as the flow through a transonic or supersonic compressor cascade. With regard to a system developed by us, a graphics work station having the power of the superminicomputer was connected with an image recorder which can control a 16 mm movie camara, and we have developed a computational code with the UNIX System which can calculate any flow and make the visualized film from the results at the same time. In particular, we can make an animation visualizing the unsteady transonic cascade flow within a half-day at most with no effort, Therefore, we should emphasize that the present system is one of the most effective tools for simulating unsteady flows.
