Enhancing the efficiency and speed of heat transfer using shell and tube heat exchanger design

Abstract

The Heat Exchanger requires the least amount of initial investment and continuing maintenance while transferring energy at a maximum or minimum rate from a hot fluid to a cold fluid. With this technique, fluids are never mixed. Because they are used at high pressures and temperatures, Shell and Tube Heat Exchangers are always being improved in terms of efficiency and heat transfer rate. In this study, we suggest a design technique for a shell and tube heat exchanger that can increase the efficiency and rate of heat transfer. It consists of a tube, a tube inlet, a tube outlet, a shell, a shell inlet, a shell outlet, baffle plates, a circular tube bundle, and a baffle pitch. Three alternative pitches-Pitch-80, Pitch-60, and Pitch-40 with similar hot and cold water temperatures were taken into consideration when designing the heat exchanger described here. The helical baffle construction with Pitch Layouts is modified with varied specifications using Pitch-80, Pitch-60, and Pitch-40 and simulated with ANSYS R19.2 in the current invention (Fluent).
