Main Article Content
This paper presents a collection of research studies related to effect of baffle shapes on flow and heat transfer in shell-and-tube heat exchanger (STHX) with baffles installed the shell side. The baffles are offered traditional segmental baffles, disc-and-doughnut baffles, continuous and noncontinuous helical baffles, combined multiple shell-pass STHX with continuous helical baffles, and trefoil-hole baffles. The research studied both experimental and numerical investigations. Conclusion, the noncontinuous helical baffles with helical angle of 40◦ optimize the performance of STHX. In addition, the numerical method is efficient for the analysis of fluid flow and heat transfer.
