摘　　要：针对建筑风场数值模拟,利用有限体积法建立了与任意六面体同位网格系统相适应的压力校正方程,给出了详细的压力校正方程离散形式.编制了相应的建筑风场数值模拟程序WSB.对双坡屋面建筑模型的风场数值模拟的结果表明:任意六面体同位网格系统中SIMPLE算法的计算效率高、收敛快,能够通用于比较复杂的建筑风场数值模拟.An in - house computer program, named Wind Simulation of Buildings （ WSB ）, has been developed in this study to model wind field around buildings, This program is capable of automatieally generating collocated grids consisting of arbitrary hexahedrons, based on which the governing equation is discretised, This unifies the way in which the governing equation is discretised and ensures the generality of the program. The wind field around a double - sloped building model is simulated by the developed prugram to validate the proposed method. The numerical resuhs are compared with the wind tunnel tests, h has been dcmonsirated that the prolapsed method is more effective,accurate and general.
