Fluid Finite Element Analysis for Hot-Air Valve Duct

Abstract:

Hot-air valve can be easily ineffective during the operation due to the bad influence of the eddy heat on the bottom outer-edge of the valve plate. COSMOSFloworks software was used to analyze the flow field of DN1800 hot-air valve duct in a certain domestic company, by adopting the classical formula of heat transfer theory’s convective recuperative system as reference. The analysis results showed that during the beginning opening of hot-air valve duct, the bottom outer-edge of valve plate receive the influence that the hot-air enforce convection heat exchanger, while during the late opening of hot-air valve duct , the bottom outer-edge of valve plate receive the influence of eddy heat exchange. Based on this analysis , the paper suggests the measures which bring down the temperature of outer-edge of valve plate .
