“…Based on the experimental data, a correlation was proposed, assuming that the heat transfer to boiling potassium obeyed the known power dependence on heat flux typical of nucleate boiling and caused by the variation of the number of acting vaporization centers with the increase in heat flux. Experimental data on potassium pool boiling and boiling in tubes [28] and on sodium potassium boiling in pin bundles were gathered by Sorokin et al [25] and a correlation was obtained based on the data.…”
