Numerical Modeling on the Performance of the Wind Tower Integrated into the Storied Building for Reducing Electrical Energy Consumption for Spaces Cooling

Abstract

Natural convection in integrated wind tower into a high storied building is numerically investigated by solving natural convection equations with the Boussinesq approximation. The present investigation deals with velocity and temperature distribution in a wind tower integrated into a high building divided into three stories; in which the upper horizontal heated wall is vented by a fresh air jet entranced by the wind tower and hot waste air exits from different outlet openings. The purpose of this study is to evaluate the Performance of integrated wind tower into the storied building, thus providing a wind and buoyancy factors for induced natural ventilation to drive air flow through the floors. Numerical solutions of the Navier Stokes equations and energy equation have been solved by the Thomas’ algorithm. Solutions are presented for various geometrical aspect ratios and for different values of Grashof and Reynolds numbers. The results are presented in terms of streamlines, isotherms, velocity, and heat transfer intensity versus the governing control parameters in detail.
