Abstract: Heat transfer is the terms use for thermal energy transfer from a hot to a colder body. Heat transfer is considered as transfer of thermal energy from physical body to another. Heat transfer is the most important parameter to be which is measured as the performance and efficiency of the shell and tube heat exchanger. CFD is the science of predicting fluid flow, heat transfer, mass transfer, chemical reactions, and related phenomenon by solving the mathematical equations which govern these processes using a numerical process. By using CFD Simulation software, it can reduces the operation cost as well as time compared by Experimental in order to measure the optimum parameter and the behaviour of this type of heat exchanger, conclusion from this project work is using CFD analysis instant results can be obtained. Temperature at any moment or point can be procured during the process. Flow patterns can be visualized which is not possible in case of experimental analysis. Also internal geometry is visible.
