Role of Plant Buildings in a Power Station Acting as a Barrier to the Wind Affecting the Natural Draft Cooling Tower Performance

The effect of wind on the performance of a cooling tower has been investigated taking into consideration plant buildings and the presence of another tower.The results include measurements from a full scale tower, wind tunnel testing and numerical simulations.It has been found from these data that the plant buildings can significantly improve tower performance depending on the wind direction relative to the buildings.However, surprisingly, when the wind is blowing from the direction of the second cooling tower, the performance of the first cooling tower drops.This paper presents some results which demonstrate the importance of buildings in predicting cooling tower performance.
