| In the present work, numerical investigation of heat transfer enhancement in a" double pipe heat exchanger" embedded with extended surface on the inner tube's outer surface with the addition of" Alumina nanofluid" has been carried out. Through the annuli, water with varying mass flow rates (0.03 to 0.07) kg/sec and hot de-ionized water with varying Reynolds numbers (250 to 2500) flows, while hot de-ionized water flows through the inner tube. One type of nanoparticle (Al2O3) having volume concentrations (1%, 3%, and 5%) was used during simulation. Numerical analysis was performed using CFD, and the Solid works was used to generate the model. A SIMPLE technique was used to solve the governing equations and discretized using the finite volume method. The simulated results show that the using of a finned tube heat exchanger resulted in an improvement ratio between (2.3) and (3.1). The coefficient of convective heat transfer increased numerically as the volume concentration and Reynolds number increased. The heat transfer coefficient and thermal conductivity rise by 20% and 4.7%, respectively, at a volume concentration of 5%. |
