Thermal design of tube and shell type Heat exchanger –a review

Abstract

A feature of heat exchanger design is the process of specifying a design. Heat transfer area and pressure drops and checking whether the assumed design satisfies all requirement or not. The idea of this paper is how to design the shell and tube heat exchanger which is the majority type of liquid –to- liquid heat exchanger. General design consideration and design processes are also illustrated in this paper. In design computation HTRI software is used to check the manually calculated results.

KEY WORDS: heat exchanger, constructional details, pressure drop, heat transfer coefficient, TEMA .Logarithmic mean temperature difference (LMTD)
