Abstract

The evaporation of water containing various amounts of dissolved electrolytes is a common engineering problem. To investigate the effects of dissolved salts on the mechanisms of pool boiling heat transfer, experiments were performed for a range of calcium sulphate and sodium sulphate concentrations in water. Bubble departure diameter, bubble frequency and nucleation site density were recorded for each experiment. The results of these experiments are compared with results from measurements with pure water. The effects of dissolved salts on bubble formation and on the formation of deposits on the heat transfer surface are discussed.
