ANALYSIS AND EXPERIMENTATION OF SHELL AND TUBE HEAT EXCHANGER WITH DIFFERENT ORIENTATION OF BAFFLES

Abstract

An Experimentation along with CFD analysis is carried on single pass, counter flow shell and tube heat exchanger containing Baffles at 00 ,150 orientation. To
study the heat transfer rate and pressure drop of shell side fluid and compare the result with Bell-Delaware method.. Experimental setup is validated with help of Dittus- Boeltercorrelation. Nusselt number obtain from Experimental set up of 00orientation and Dittus- Boeltercorrelation are within 5.72%.Experimental result of 00 orientation is also compare with CFD results in which Nusselt number are found to be within 12.50% and pressure drop is found within 5.55%.Results obtain from CFD analysis is also compare with Bell Delaware method and Nu in case of CFD is 3.35% of Bell- Delaware. . From this experimental, CFD and Bell Delaware analysis it is found that as baffle angle changes from 0 to 45 degree Nusselt no. is increases that is indirectly heat transfer rate is increase and pressure drop is
reduces.Reduction in Pressure drop with increase in baffle orientation help in reducing the pumping cost of Shell and tube heat exchanger.
