Abstract

Abstract An experimental investigation on the validation of Cooper correlation at the heat flux of 10,000 to 370,000 W/m² is conducted with refrigerant R134a. The slope of best-fitting straight line for heat transfer coefficient versus heat flux is mostly of 0.67 at heat flux less than 250 kW/m². A sustainable decrease of slope is observed when heat flux is larger than 250 kW/m². At the higher heat flux greater than 250 kW/m², a significant deviation of experimental data and the prediction result of Cooper's correlation is observed. The valid range of heat flux for Cooper's correlation to predict the pool boiling heat transfer of R134a should be less than 250 kW/m².
