Computation of wind flows over three-dimensional buildings

Abstract A computer program has been developed to compute turbulent flows over three-dimensional rectangular surface-mounted bluff bodies and the results have been applied to wind flows over buildings. The program solves the steady-state Reynolds equation using a κ—ϵ model of turbulence. The resulting differential equations are solved by the use of the SIMPLE algorithm. Four flows have been studied and the computed results compared with full scale and wind tunnel measurements carried out by others. Good agreement has been obtained in most cases.
