Abstract

The aim of this research is to find the adverse effects of the cross wind on the performance of natural draft dry cooling towers and to reduce these effects by changes in the external shape of the cooling tower. The results have indicated that the cause of the wind effect can be attributed to the around flow effect at the bottom of the tower and the cap effect (wind-cover) at the tower outlet which decrease the cooling tower air flow. In this paper using the finite volume method, the fluid flow around and in a tower was simulated numerically. The results have indicated improvement in the performance of cooling tower when wind break walls are used at the inlet and a special wind break wall at the top of the tower.
