Numerical Simulation Research of Aerosol Cooling

Abstract

Through the establishment of the mixture model and the discrete phase model of aerosol cooling, the heat transfer characteristics between the aerosol and high temperature die steel plate are studied. When the discrete phase volume fraction is greater than 10%, mixed convection heat transfer model is used to study the effect of the gas-water volume fraction on heat transfer characteristics; when the discrete phase volume fraction is less than 10%, the discrete phase model is used to study the effect of the discrete phase mass flow rate and particle size on the heat transfer characteristics. The results can provide important references for the die steel quenching equipment design and production.
