Hydromagnetic Convective Radiative Heat Transfer Flows Of Nanofluids Through Porous Medium In Channels And Over Extended Surfaces

Abstract

The aim of this work is to study the hydromagnetic convective-radiative heat newlinetransfer flows of nanofluids through porous medium in channels and over extended newlinesurfaces on various geometries like fins, multilayer flow, stretching sheet and newlineconvergent and divergent channel. The several condition and effects are incorporated newlinein the fluid model such as variable thermal conductivity, Lorentz force, buoyancy force, newlineelectric field, porous medium, thermal radiation, chemical reaction, joule heating, heat newlinesource/sink, thermophoresis, Brownian motion, soret and dufour effect. The governing newlineequations are derived for, those equations are converted to dimensionless equations by newlineusing suitable similarity transformations or dimensionless parameters. The obtained newlineresultant equations subjected to relevant boundary conditions are solved using newlineanalytical/numerical methods with the help of open software s. The effects of different newlinenon-dimensional parameters on the velocity, temperature and concentration are studied newlinethrough graphs. Additionally, the derived quantities Skin friction, Nusselt number and newlineSherwood number are analysed. They are studied by surface graphs and also by newlinestatistical techniques like Response Surface Methodology (RSM) and Artificial Neural newlineNetwork model (ANN). Various problems which will be investigated in this work have newlinenumerous applications in geophysics, nuclear power reactors, solar collector and also newlinein biomedical applications. newline
