摘　　要：利用ANSYS中的Fluent模块,对东京工艺大学风洞试验采用的一低矮双坡房屋模型进行数值模拟,并对比分析数值模拟与风洞试验结果,证明了采用数值模拟研究此类问题的可靠性。在此基础上,利用数值模拟研究了4种山体排列对低矮双坡房屋屋面风压的影响,并给出了相应情况下的屋面体型系数,供设计参考。The Fluent module in ANSYS is used to simulate a low-rise gable-roofed building used in the wind tunnel test at Tokyo Polytechnic University,and the simulation results and wind tunnel test results are compared.It is proved that the numerical simulation is used to study such problems.On this basis,the influence of four kinds of mountain arrangement on the wind pressure of low-rise gable-roofed building is studied by numerical simulation,and the body shape coefficient of the corresponding situation is given,which can be used as a design reference.
