The strong wind flow affected by mountainous terrain generates occasionally a big gust, causing serious damage to houses, trains and so on. Generally, it is known that intensities of turbulence simulated by Computational Fluid Dynamics (CFD) are smaller than those associated with wind tunnel experiments and wind observations. We are sure that those are resulting from the insufficient grid resolution of a flow field around, mountainous terrains in a CFD model. In this paper, we show experimental results on the leeward side of a mountainous model are reproduced by CFD analysis with a fine resolution using 64-bit Windows PC. That is, CFD analysis using 64-bit PC can simulate more accurately wind tunnel test results.
