Augmenting Heat Transfer of Shell and Tube Heat Exchanger – A Cfd Analysis Approach

Abstract

Abstract A shell and tube heat exchanger journal that has undergone experimental analysis is used as a guide. There are four different segmental baffle layouts employed in the referred journal. The four types of baffle layouts are flower segmental baffle (FSB), hybrid segmental baffle (HSB), staggered single segmental baffle (SSSB), and conventional single segmental baffle (CSSB). STHX using CSSB by itself was examined in this paper. Since heat transmission is the foundation for the shell and tube heat exchanger's (STHX) performance. We added twisted tape inside the tube and used helical baffles in place of the traditional baffles to improve it. In this research, four varieties of STHX have been constructed and simulated. The STHX with helical baffle, STHX with helical baffle and twisted tape, and STHX with CSSB and twisted tape are the four variants. For the chosen shell and tube heat exchanger, theoretical calculations are performed, and the outcomes are compared with the experimental journal. The STHX was created and simulated in the HTRI Xchanger suite using the theoretically derived value. The STHXs are created and put together in SolidWorks, and then the file is exported to FLO EFD for CFD analysis.Four STHX configurations' simulation results were compared, and it was found that the new configurations—STHX with helical baffle, STHX with twisted tape, and STHX with CSSB and twisted tape—had a noticeably better heat transfer enhancement. For every test situation, STHX with a helical baffle and twisted tape arrangement had a greater impact on improving heat exchanger performance than the other configurations.
