Research the Wind Effect on the Fans Performance of Air-Cooled Condenser for Geothermal Power Station

The results of numerical studies of the wind effect on the fans performance of the air-cooled condenser (ACC) for geothermal power plant using CFD (Computational Fluid Dynamics) are presented in the article. We consider the modular design for the ACC with a lower positioning of the fans. 3D model of the ACC with surrounding buildings, units and landscape elements is used. Heat transfer surfaces are replaced by anisotropic filter with specified characteristic of total pressure losses, while the fans are presented by filters with head-flow characteristic of the serial fans. Calculations were carried out for the wind from 4 to 30 m/s with four orthogonal directions and the prevailing direction in accordance with the wind rose. Calculations shows the presence of a cluster effect in the considered design ACC, a significant effect of wind direction and speed on performance of module ACC fans.
