ANALYSIS OF THERMAL STRESSES IN HEAT EXCHANGER TO FIND OPTIMUM WALL THICKNESS THROUGH ANSYS

Abstract

External natural convection heat exchangers have evolved as a suitable alternative to forced convection as a means to transfer energy from hot fluid to cold fluid in hot water storage tanks. Determination of performance characteristics of these convection heat exchangers require complicated and lengthy experiments and such a practical problem has been raised during the experimentation of a research work in the heat transfer laboratory. This work uses ANSYS to predict the intensity of thermal stresses induced during heat transfer in the walls of heat exchanger and to find optimum thickness of heat exchanger wall without affecting heat transfer rate. In this research work a heat exchanger wall with two different thickness values 1.2 mm & 1.5 mm is modeled through ANSYS to study the behaviour of thermal gradient.
