AB - This research is to incorporate three efficient ways that will increase the  performance of baffled heat exchangers. The 1st technique is represented by  baffle perforating to create pores through which secondary streams pass in  order to reduce main stream pressure on the flow areas. A 2nd technique  represented in redesigning the baffle structure by replacing its square  edge with the arched edge in order to increase the X-velocity to facilitate  the flow towards the outlet and reduce the Y-velocity to reduce the values  of fluid friction with the solid areas. Finally, a 3rd way was demonstrated  by using the inclined baffle model. Reinforcement of the baffle structure  allowed for enhanced vortices, increased thermal gradients, and thus a  reinforced thermodynamic structure over the entire heat exchanger.
