Numerical simulation of dispersion around a cubic building: characterization of wind-induced pressure coefficients on cube using Standard K-ε Model

Abstract

The aim of the work is to determine the total pressure coefficient ( ), the behavior of pressure and pressure coefficient  near the walls of cube (roof and floor of cube) to study the effect of  on the behavior of flow and reverse flow on the top of cube due to wind tunnel, which allows the pressure due to the wind at the cube faces (negative pressure ( < 0) or overpressure (  > 0) compared to the static pressure (atmospheric pressure)) to be quantified. This coefficient depends on the wind velocity (W) upstream the cube (velocity in the wind tunnel), on the geometry of obstacle (which is cube used here) and on the attack angle of wind.
