| Résumé : |
The aim of this work is to study numerically the laminar mixed convection and
entropy generation in cavities. The calculations were performed for water (Cu, Ag)
metallic nanofluids and water-(AlO3, TiO2) metal oxides. The fluids are supposed
incompressible and Newtonian. The equations governing the flow and heat transfer have
been solved using the finite volume method. A house code in FORTRAN has been
developed to calculate the flow and temperature fields, the Nusselt number, and the
entropy generation. The effects of Rayleigh and Reynolds numbers , the volume fraction
of the nanofluid, the nanofluid type, and the position of the heat sources on the flow and
thermal fields, the average Nusselt number, entropy generation, and the Bejan number
are studied in detail. The results show that the use of nanofluids improves heat transfer
and reduces the entropy generation. Finally, a three-dimensional numerical study of
laminar forced convection in a cubic cavity filled with different nanofluids is presented.
In this study, the Ansys-Fluent 14 software was used to solve the equations of the
problem in question |
