In the present paper, heat exchanger is of shell and tube type is proposed three models are compared with each other. The model predicts the heat transfer and pressure drop. In this computational fluid dynamics (CFD) technique which is a computer based analysis is used to simulate the heat exchanger involving fluid flow, heat exchanger. CFD resolve the entire heat exchanger in discrete elements to find the temperature gradients, pressure distribution and velocity vectors. The turbulence model k-ɛ is used for accurate results from CFD and the model can be rectifying in order to acquire improved heat transfer in twice ways. Either, reduce the shell diameter to keep the outer fluid mass flux lower or tube spacing can increase to enhance the inner fluid mass flux. Just doing this might not be enough, because it is seen that the shell side fluid after 3 m doesn’t transfer heat efficiently.it is because the heat transfer area is not utilized efficiently. Thus the design can further be improved by creating cross flow regions in such a way that flow does not remain parallel to the tubes. It will allow the outer shell fluid to mix with the inner shell fluid and will automatically increases the heat transfer.
