Numerical Study Of Direct Air Cooling Units Cooling Island And Air Cooling Island’s External Flow Field Based On The Way Underground Inlet

This paper analyzed the current problems on the ground direct air cooling unit andproposed underground into the wind that the air-cooled platform placed lower, Wind raninto the underpass entrance far from one hundred meters, Platform above the groundwalled by the wind wall. air enters the condenser heat only through the undergroundpassage. we tentatively proceeds to making numerical simulation research on the600MW direct air-cooled unit into consideration by using CFD software Fluent,FoundAnalysis of temperature and velocity field of air-cooled island, Calculate the amount ofwind turbine in different environment wind、condenser outlet air temperature、condenserheat transfer efficiency；Draw the wind wall height and condenser heat exchanger graphto reflect the superiority of the underground into the wind by the resurch of Heighteningthe direct air cooling unit wind wall.
