Abstract

Abstract

The characteristics of wind pressures distribution on the single and double hemispherical dry-coal-sheds with day-lighting ceiling were investigated by using CFD.Compared with the wind pressures gained by wind tunnel tests in reference,the CFD results were credible.Base on the CFD results,the influences of terrain types,wind directions and interference conditions on the block shape coefficients and drag force and lift force coefficients were discussed.Finally,the block shape coefficients and drag force and lift force coefficients of the total structure were given in the non-interference and interference conditions,which were suitable for engineering application.
