dc.description.abstractThe Al2O3 (aluminum oxide)-water nanofluid is utilized in this study to improve the overall performance of a parallel flow thermal exchanger with two coaxial tubes. Numerically, the impacts of hot fluid flow, flow direction, and nanoparticle volume fraction on thermal fields, Nusselt number, and device performance are investigated. The hot fluid’s Reynolds number ranges between 3054 and 7636, whereas the cold fluid’s is set at 3000. The two-equation k-? SST turbulence model is used to accomplish the numerical simulation. The validation of numerical findings reveals a satisfactory match with the experimental reported values. The obtained results reveal positive effects of increasing fluid flow rates and nanoparticles concentration on the performance of the double-tube thermal device and Nusselt number, especially in the counter flows configuration.en_US
