Development of Experimental Device for Spray Cooling and Study on Cooling Characteristics of Porous Foam

Long Huang, Yujiao Wang

Abstract


In order to study the interaction between foam and working medium in the process of spray cooling heat transfer, a spray cooling experimental device was developed to study the interaction between foam and working medium in the process of spray cooling. The results show that the presence of foam can improve the heat transfer coeffi cient of the working medium in the spray cooling process, so as to improve the heat transfer capacity. The foam has a strong adsorption effect on the working medium, which reduces its viscosity. Foam can also reduce the interfacial tension of gas and liquid, promote the mass transfer process of the working medium in the spray cooling process, and improve the heat transfer capacity.
