Abstract

Because shell and tube heat exchanger is widely used in industry, extensive research work is going on to improve the thermal efficiency and to understand the key design parameters. In this study, the main design parameters of the baffle, depending on the height and number of baffle for heat recovery are being studied. Numerical results are in good agreement with the experimental results with a slight discrepancy of 3%, which is quite resonable. The heat transfer rate and pressure drop increase depending on increasing of number of baffles and baffle height, but increase of the heat transfer rate is limited due to contact area with the tube, flow separation, fluid residual time, turbulence and velocity.
