Abstract
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.
