A generalized correlation of nucleate pool boiling of liquids

Abstract

An experimental study on nucleate pool boiling of distilled water, benzene and toluene from a horizontally laid plain stainless steel heating tube at atmospheric and subatmospheric pressure has been discussed here. The main objective of the investigation is to study the variation of heat transfer coefficient around the circumference of heating tube and thereby to determine functional relationship of local and average heat transfer coefficient with heat flux and pressure. Further, a generalized correlation of boiling heat transfer coefficient of various liquids has been developed to examine the consistency of experimental data conducted on heating surfaces of different characteristics.
