Abstract
In this paper, the design and performance optimization of porous baffles in shell and tube heat exchanger (STHX) are systematically investigated through numerical simulation and response surface methods.The study focuses on the effects of key parameters such as baffle cut, porosity and number of tubes on the total heat transfer and pressure drop of the STHX.
