Field study on airflow pattern through radiator of Heller dry cooling tower

Wind is one of the factors influencing the performance of the dry cooling tower. According to research، wind will decrease the efficiency of dry cooling tower about 20%. Therefore، many studies have been done to improve the performance of dry cooling towers. Although various numerical methods and wind tunnel studies have been conducted، but the data obtained has not been properly validated and therefore requires that the appropriate field research done. To study the effect of wind on the performance of dry cooling tower، it is appropriate to model airflow around the cooling tower and the entrance of the deltas. In this research، which is the field research، air flow pattern around the tower and the deltas of Montazar ghaem plant cooling tower has been evaluated. The survey results found that the flow around the cooling tower has no separation. The sectors are positioned in front and back of the wind have the most efficiency and the least efficient sectors that are tangential to the wind. There is a vortex flow pattern in the critical deltas.
