Abstract
after reviewing the progress in Computational Fluid Dynamics(CFD) that have take place for the past two decades, this article describes the present status of the leading-edge applications of CFD in engineering fields, and provides the author's personal forecast how CFD will develop in the coming decade, Even larger-scale computations that utilize several tenth billion computational grids will become feasible where such computations are expected to give the same level of accuracy that DNS(Direct Numerical Simulation) does. Along with this progress in the large-scale computations, the mathematical model for multi-scale physical phenomena such as aeroacoustics, cavitation, and combusting flows will also be advanced.Another progress expected for CFD is the achievement of very-fast computations of RANS (Reynolds Averaged Navier Stokes Simulation) and this will enable the full optimization of product design based on the results of CFD. This article also gives comments on those problems that have to be overcome in order to realize the expected achievements for CFD.
