The purpose of this paper is to design the shell and tube heat exchanger for Diesel Locomotive. A characteristic of heat exchanger design is the procedure of specifying a design, then calculating the heat transfer coefficients, heat transfer surface area and pressure drops and checking whether the assumed design satisfies all requirements. The inlet temperature of shell and tube heat exchanger is about 86°C. This temperature must be cooled down to a constant temperature 78°C. The design has been done using Bell Delaware method in order to obtain various dimensions such as shell, tubes, baffles etc. Then the thermal simulation in COMSOL Multiphysis has been performed by applying several thermal loads on variable baffle number. Viscous fluids go on the shell side, since this will usually improve the rate of heat transfer.The pressure values from the simulations results compared with theoretical.
