Evaluation of Pool Boiling Heat Transfer Coefficients for the Data of Engelhorn.

Abstract

Engelhorn has conducted experimental work to determine nucleate pool boiling heat transfer coefficients for a variety of refrigerants at wide pressure and heat flux range. In this work we have compared the experimental data of Engelhorn for refrigerants R-11, R-12, R-13, R-13B1, and R-22 with those calculated from the correlation which is based on two factors which are responsible for the removal of heat from a heat transfer surface in boiling. The first factor represents heat removal by transient heat conduction and the second factor represents latent heat transport removal. The data were compared for pressures ranging from 0.019 bar to 1.51 bar and the heat flux ranging from 100 W/m2 to 102,000 W/m2. The calculations revealed that experimental and predicted heat transfer coefficients compared very well.
