摘要
应用紊流大涡模拟方法对建筑物环境风场进行了数值模拟。采用尤拉观点引入大涡模拟法作为风场的紊流模式,并采用SIMPLE法求解环境风场流场。数值计算结果与实验符合较好,表明紊流大涡模拟比标准的k-ε紊流模式具有较高的可靠性。
The large eddy simulation approach is applied to airflow field around buildings.The wind flow model and Eulerian approach are used to simulate airflow pattern and large eddy simulation of turbulent flow is conducted while SIMPLE method is employed to solve the wind flow field.At last,the wind-flow model is verified by available wind tunnel measurement.It is found that the results gained by large eddy simulation method is more reliable than that obtained by standard turbulent model.
