Numerical Simulation of Airflow Field around Buildings

Peng Rong-qiang

Abstract

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.
