Proposing a Configuration for Heller-type Cooling Tower to Reduce UndesirableWind Effects

Cooling tower is one of the most important units used in the power plant. Thermal efficiency of the power plant is directly affected by thermal performance of the cooling system. Thermal performance of the Heller type cooling tower is significantly reduced in the wind condition as same as the other dry-cooling towers. Thermal performance of the cooling tower may be reduced up to %40 during high speed wind condition. It is due to separating flow around the radiators and deflected exit plume at the top of the tower stack. In the present research work, a special configuration was proposed for Heller-type cooling tower to reduce the undesirable wind effects. Numerical simulations of the flow field showed that, it could increase the thermal performance of the cooling tower up to %64 regarding the usual design configuration. This proposal is a cooling tower having 20×20 (m2) windbreakers and exit plane making angle of 27o with horizontal direction.
