Heat transfer has become one of the basic needs in the manufacturing and refrigeration industry. Optimizing system performance and minimizing the use of available resources is always been the focus of researchers. Therefore, in this study, it was decided to conduct a Computerized Fluid Dynamics (CFD)based study on heat transfer variations in terms of properties of thick materials using rings as roughness geometry. An electronic exchange model was developed in Solidworks to generate the roughness of the inner tube. The effect of surface roughness on the efficiency and friction coefficient of counterflow heat exchangers was analysed. In addition to it, to predict the performance of counterflow heat exchanger, the dependence of efficiency and friction coefficient as a function of Reynolds number and relative roughness height has been established. The data so obtained through CFD simulation was in good agreement with predictions based on design value and friction coefficient.
