Numerical simulation research on the aerodynamic performance of concave building section

Abstract Analysis the aerodynamic performance to concave building section through numerical simulation calculation, adopt two different turbulence models: Standard k ɛ−& Realizable k ɛ − to simulate calculate the shape factor of the section from different wind angle, comparing with standard value in order to investigate the applicability of turbulence models for numerical simulation of blunt body flow around, and analysis the structure of flow field. Finally, get the wind environment characteristic of the section at different wind angle, and calculate to get the shape coefficients of the section at specific wind angle.
