Abstract

Abstract:

Taking a 600 MW direct air-cooling unit as an example, the influence of environmental wind on the heat transfer efficiency of air-cooled condenser was numerically simulated by using CFD software （Fluent）, and the schemes of different windshields installed around the air cooling platform were put forward. The calculation results show that the installation of windshield can reduce the influence of hot air recirculation and the ‘intrusion’ phenomenon, as well increase the air flow in air cooling unit and the average heat transfer of condenser, which can be up to 72.52% and 24.51% higher than that without windshield, under 0 m/s-12 m/s environmental wind speed.

Key words: direct air-cooling unit, condenser, windshield, numerical simulation, heat transfer efficiency
