The study deals with CFD simulation of concentric tube heat exchanger and concentric tube heat exchanger with insert used for heating air using ANSYS FLUENT Software for steel. Design process for heat exchanger and insert has been carried out in SOLIDWORKS, fluid domain is formed in ANSYS workbench, followed by meshing in default mesh tool of ANSYS and solution is developed using ANSYS FLUENT software as FINITE ELEMENT TOOL and the results are compared between the two designs for parallel flow. The Reynolds number of air varied from 21000 to 100000. Inlet temperature of hot water and cold air are 60̊ C and 26̊ C respectively. The work included the determination of Nusselt number, heat transfer coefficient and friction factor for insert in parallel flow and counter flow.
