    Thermo-Convective Study of a Hybrid Nanofluid with Entropy Generation
    (20 août 1955- University Skikda, 2025) Maissa, Bouselsal; Mebarek, Oudina
    In this paper, forced convection and entropy generation in a shell/tube heat exchanger are studied numerically. We ran the computations for various hybrid nanofluids. The finite element method has been used to solve the equations governing the flow and heat transfer. To compute the flow and temperature fields, the Nusselt number, and the entropy production, a COMSOL Multiphysics algorithm has been built. In-depth research is done on the effects of Rayleigh and Reynolds numbers, the nanofluid type and volume percentage, the various tube radius effects, the average Nusselt number, and entropy generation. The findings demonstrate that the application of nanofluids enhances heat transmission while lowering entropy production. Lastly, a numerical analysis in three dimensions of laminar forced convection in a shell/tube heat exchanger containing various nanofluids is showcased.
