本文以Ｒｅｙｎｏｌｄｓ时均方程为基础，运用一种扩展ｋ－ε湍流模型对建筑物在近地风作用下的表面风压进行了数值模拟。利用ＮＤＰＦＯＲＴＲＡＮ优化编译器在微机上实现了三维问题的模拟计算，对模拟程序的主要模块进行了剖析。文中对一５５ｍ高矩形横截面建筑物的表面风压进行了实例计算，计算的风压值与标准ｋ－ε模型的相应值以及边界层风洞试验的测试值作了比较。结果表明微机上的风载数值模拟是可行的，且模拟结果与试验值有较好的吻合。
Based on the Reynolds time-averaged equation, the paper uses an extended k-ε turbulence model to simulate the surface wind pressure of a building under near-Earth wind. The NDPFORTRAN optimization compiler was used to simulate the three-dimensional problem on the microcomputer, and the main modules of the simulation program were analyzed. In this paper, the surface wind pressure of a 55m-high rectangular cross-section building is calculated. The calculated wind pressure value is compared with the corresponding value of the standard k-ε model and the test value of the boundary layer wind tunnel test. The results show that the wind load numerical simulation on the microcomputer is feasible, and the simulation results are in good agreement with the experimental values.
