Magnetohydrodynamic (MHD) stagnation point flow of Casson fluid over a stretched surface with homogeneous–heterogeneous reactions

Abstract

This article communicates the study of magnetohydrodynamic (MHD) stagnation point flow of Casson liquid towards a stretched surface. Chemical reaction model involving both heat and mass transfer is established. Effects of viscous dissipation and Joule heating are also considered. Appropriate transformations yield strong nonlinear ordinary differential system. The obtained nonlinear systems have been solved through built-in shooting method. Velocity field shows decreasing behavior for higher estimation of magnetic parameter while temperature field shows increasing behavior for larger homogeneous heat parameter. Graphical behaviors of velocity, temperature and concentration are analyzed comprehensively corresponding to various pertinent parameters.

On heated surface transport of heat bearing thermal radiation and MHD Cross flow with effects of nonuniform heat sink/source and buoyancy opposing/assisting flow

“…Moreover, they discussed over a stretched surface, transfer of heat in magnetohydrodynamic (MHD), and stagnation point flow of Cross fluid. Khan et al 5 worked on transformation of heat in MHD numerically simulation. Mehwish et al 6 showed her work on convection of heat transfer in a cross fluid.…”

Interpretation of entropy generation in Williamson fluid flow with nonlinear thermal radiation and first‐order velocity slip

“…In the last couple of decades, engineers and researchers have been carried out examinations on the important characteristics of fluid flow and heat transfer subject to various assumptions. Combustion problems have been widely studied in a radiated flow towards a stretched and flat surface by numerous analysts 16–29 …”

“…Combustion problems have been widely studied in a radiated flow towards a stretched and flat surface by numerous analysts. [16][17][18][19][20][21][22][23][24][25][26][27][28][29] The present communication, therefore, aims to scrutinize and thus provide awareness on how entropy optimization in radiated flow towards a flat surface of sheet is affected due to variables, that is, magnetic parameter, Darcy-Forchheimer number and radiation parameter, and the type of flow. It is trusted that this would prompt expanded understanding in the current knowledge of heat transport and entropy generation minimization and allow engineers and researchers to design such types of mathematical modeling that not only accomplishes the desired objective in term of heat transport and entropy generation minimization.…”

Electromagneto squeezing rotational flow of Carbon (C)-Water (H2O) kerosene oil nanofluid past a Riga plate: A numerical study

“…Hayat et al [ 39 ] studied the impact of homogenous-heterogeneous reactions in boundary layer flow of nanofluid saturating porous medium in presence of melting heat transfer. Few studies on heat and mass transfer can be found through the refs [ 40 – 43 ].…”
