Optimization Design of Installing Windshield Board On Natural Draft Wet Cooling Tower

Based on the relative theorise of the wet cooling tower,this simulation builds the heat and mass transfer model through CFD.The main heat transfer area,such as fillers,rain and spray zone discrete phase model.As the air temperature is low in winter and the heat transfer is uneven in the tower,the water is easy to freeze below the packing of the cooling tower,at the air inlet and on the base torus.A method is presented that a wind shield is installed at the air inlet,numerical simulation results show which improves the temperature field in the tower and effectively prevents freezing.
