Open publisher page 0 citations

Abstract

Taking a hyperbolic natural draft cooling tower of 300 MW thermal power unit as research object,effect of crosswind to cooling tower performance and air inlet velocity field are analyzed. These researches of numerical simulation are based on the Fluent Software. Researches show that cooling temperature difference will decrease first and then increase,outlet temperature of the tower will increase and then decrease with the increasing of cross-wind velocity. Air inlet velocity field of the cooling tower will be disturbed by the existence of the cross-wind,of which the critical wind speed is 6m /s.
