摘要

The objective of this study is to investigate applicabilities of the computational fluid technique to the wind resistant problems of buildings and structures. it is important for the evaluation of aerodynamic characteristics to grasp the unsteady behavior of separated flows and the vortex structures around a building. Therefore, we use the interpolation method on the staggered grid system. According to the previous computational examples for the fundamental flows, the predicted values by this method are in good agreement with those obtained by the spectral method.
