Heat exchangers are widely use in during the condensation, evaporation, oil refineries, other large petrochemical plants and automobile function. Shell side analysis of single phase shell with tube heat exchanger during particular stream rate and baffle slant angle dependencies of the pressure drop , heat transfer rate and heat transfer coefficient be investigated by numerical models for both horizontally and vertically placed baffle cut.. The geometry of the model is made in SOLID EDGE v19 and

During current work attempt were prepared to examine the impacts of different baffle slant angle namely 150, 250 with various stream rates namely 1 kg/s, 2 kg/s. The 36% baffle cut and 16% baffle spacing is used for modeling the heat exchanger. The simulation results for single phase shell with tube heat exchanger for both horizontal as well as vertical baffle cut are compared for the performance. The outcome observed to be perceptive for the turbulence model. From the CFD simulation result 250 slant angle for stream rate of m=2 kg/s of the horizontal placed segmental baffle cut gives 9.27% decrease in pressure drop, and 51% raise in heat transfer. Horizontally placed baffle gives 0.06% better results compare with vertically placed baffle. From CFD simulation results pressure drop, shell side outlet temperature, heat transfer coefficient, heat transfer rate and recirculation near the baffles are determined.
