A Systematic Review on Thermal Analysis of Shell and Tube Type Heat Exchanger and Its Optimisation

Abstract

This paper is related to shell and tube heat exchanger, which are heat exchangers comprised of tube bundle installed in shell for flow of first fluid through the tubes called as tubeside fluids and for the flow of second fluid over and around the tubes called as shellside fluids. This paper presents an attempt to optimize a shell and tube heat exchanger of the various types of heat exchanger used in various industries, shell and tube heat exchanger is probably the most versatile and widely used in most industrial sectors. In recent years, there have been notable researches on performance of shell and tube heat exchanger mainly on the effect of baffle inclination angle, increment in heat transfer and reduction in pressure drop Shell and tube heat exchanger, Baffle Inclination Angle, Pressure drop, Overall heat transfer. The analysis has been done on shell side of shell and tube heat exchanger. Helical baffles are implemented on shell side of heat exchange which provides the helical flow to shellside fluid helps in increasing the turbulence as a result the heat transfer rate is increased and fouling is reduced. In this paper the thermal analysis of helical baffle heat exchanger gives us the idea that heat transfer rate per unit pressure drop of helical baffle heat exchanger is more compared to segmental baffle heat exchanger.
