Computational analysis of a heat transfer device integrated wind tower system for hot climate

The purpose of this study is to integrate heat transfer devices in a wind tower to meet the internal comfort criteria in extreme external condtions. Computational Fluid Dynamics (CFD) was used to develop a numerical model of a wind tower system and simulate the air flow pattern around and through the device to the test room. Results have indicated that the average internal airflow rate was reduced following the integration of the vertical and horizontal heat transfer device configuration, reductions of 4.11% and 8.21% was obtained respectively. The work also compared the thermal performance of the passive ventilation device incorporating traditional evaporative cooling and heat transfer devices. The proposed cooling system was capable of reducing the air temperatures by 12-15K.
