Measurement and Numerical Simulation of Wind Environment for One Residential District

A residential quarter in the west of Changsha has a nearby main transport corridor to the east,and Tianma Hill is to the west. The circumference of this residential quarter is open to the outside; therefore, the wind environment is special. In this study the wind environment of this area is measured and the influence factor is analyzed. Based on these testing data, some of which are regarded as the boundary conditions, this study employs the commercial software FLUENT to calculate the wind field of this district. The results are compared with the testing data. Under average wind velocity conditions of predominant wind in summer and winter, the wind environment is predicted. The numerical calculation results agree well with the testing data. FLUENT can predict the wind field effectively for varied boundary conditions. Key word: residential district, wind environment, test, numerical simulation
