Heat Transfer in Pool Boiling of H2O/LiBr Mixture

Abstract

This paper presents the results of an experimental investigation carried out to study the heat transfer in saturated nucleate pool boiling of the H2O/LiBr bromide mixture on a heated vertical copper cylindrical rod at atmospheric pressure. The mass fraction of lithium bromide was varied from 0 to 0.5. It was observed that the heat transfer coefficient increased for the mixture with an increase in heat flux and lithium bromide concentration. A correlation for the heat transfer coefficient as a function of heat flux and lithium bromide concentration was obtained with a good fit to experimental data.
