Apparently, the most common solution to enhance the performance of natural draft dry cooling tower equipped with vertical heat exchangers has been to implement windbreak walls as aerodynamic devices to compensate the unwilling pressure drop over the cooling tower under windy conditions. On the other hand, the thermo-aerodynamic solution approaches are known to be new in this field of study and there is great room to improve their design properly. This study focuses on improving the performance of natural draft cooling towers by developing new auxiliary thermo-aerodynamic components, which are the same heat exchangers used in the main cooling tower. This new device can return the negative role of strong wind to a positive one. They are simple auxiliary heat exchangers, which can be used to improve the performance of main cooling tower’s heat exchangers. To examine the impact of new auxiliary heat exchangers, eight new heat exchangers are placed at identical arcs round around the cooling tower. With the development of computers and the use of CFD simulations, it has been possible to arrive at the full flow physics without high computational costs and without experimental device cost requirements. Therefore, this study simulates the cooling systems with natural draft with auxiliary thermo-aerodynamic components numerically under various wind velocities of 4, 8 and 12 (m/s). In order to evaluate the effect of new installed components on the performance of original natural draft cooling system; the heat release is studied with and without installing the auxiliary heat exchangers. Eventually, the percentages of improved performance are discussed properly.
