The Effects of Baffle’s Design on Shell and Tube Heat Exchanger’s Performance

Abstract

The purpose of this article is to observe the effects of baffles’ design in shell and tube heat exchanger on pressure drop and thermal performance at various mass flow rates. The pressure drop and heat transfer depend on the baffles design so here different baffles are simulated to evaluate the performance and find the best and suitable baffle at high mass flow rate in shell and tube heat exchanger. In this study shell side flow is focused and simulated because turbulence in shell side flow is high and baffles are also installed there. Four different types of baffles are modeled and simulated including single segmental, double segmental, helical and single segmental plus helical. These baffles are modeled and simulated on solidworks CAD software. Simulated results has shown that the single segmental baffle has more pressure drop and less heat transfer rate but new design single segmental plus helical baffle has less pressure drop and more heat transfer rate even at high mass flow arte.
