Abstract

The motive of this research article, is to present a comparative study of entropy generation for a system of MHD mixed convection non-Darcy porous medium flow of mono and hybrid nanofluids over a melting surface. Darcy–Forchheimer model for the flow through porous medium is employed to formulate the problem under consideration. The dimensional momentum and heat equations governing the flow are transformed into a non-dimensional ODEs with the help of similarity variables. The similarity solution of the dimensionless differential equation is computed with the MATLAB’s bvp4c package. The influence of various embedded parameters on the flow fields and entropy generation are examined. The study reveals that the entropy generation in Cu−Al2O3 water based hybrid nanofluid is smaller compared to that of Cu-water based mono nanofluid. The findings of the study have bearing in the fields involving oil flow filtration, crude oil production, electronic cooling equipment etc.
