Investigation on the jet impingement/boiling heat transfer

Jet impingement/boiling heat transfer were experimentally studied using R134a as the working fluid. The heat transfer on high heat flux was studied and the fluid flow flux and latent heat of the working fluid on heat transfer were also studied. Data on heat transfer were achieved and the results show that the heat transfer coefficients were effectively improved while boiling was introduced into jet impingement. In this study, with an average liquid flow flux of 1.2 L·min^-1·cm^-2, a maximum surface heat flux of 305 W/cm² was achieved while the temperature of heater surface was 57.61°C.
