一般注記Recently, a flow analysis based on the Euler / Navier-Stokes equations has become more important and necessary in aerodynamic design. Therefore codes, based on the Beam-Warming-Steger (2-D, axisymmetric) method, have been developed in KHI to solve the Euler / N-S (thin-layer) equations. So far the calculation time required to get the final result is too long and the codes lack robustness. Some attempts have been made to improve them. This paper presents: (1) Comparison of some calculation results of KHI's Euler code with Jameson's FLO 54. (2) Application of the Multigrid method and the local-variable-time-step method to KHI's Euler code. These applications shorten the time steps needed for con-vergence. (3) Some of the results obtained with KHI's N-S code.
