The three-dimensional magnetohydrodynamic (MHD) boundary layer flow of a Casson fluid over a stretching surface set into a porous medium with variable thermal conductivity and heat generation/absorption has been researched. Conservation laws of mass, momentum and energy are changed into ordinary differential equations, which are numerically dealt with by applying the fourth order Runge-Kutta integration...
An analytical solution is presented for entropy generation on MHD Walter’s liquid B fluid over a stretching sheet with elastic deformation. The governing expressions of PDEs are converted into ODEs by suitable transformation which is solved by a hypergeometric function. Plots for velocity, heat transfer, entropy generation and a Bejan number are examined and their behavior is deliberated for several...
The effects of inclined magnetic field on entropy generation in nanofluid over a stretching sheet were investigated in the presence of partial slip and nonlinear thermal radiation. Applying a similarity variable, the governing equations are reduced to a set of nonlinear ODEs. These equations are solved both analytically and numerically by hypergeometric function and Runge–Kutta Gill method with shooting...
The effect of sinusoidal heating on double-diffusive mixed convective flow with heat and mass transfer in a lid-driven square cavity is numerically investigated. The horizontal walls of the cavity are adiabatic and impermeable. Sinusoidal boundary temperatures and concentrations are imposed along the left and right sidewalls of the cavity. The governing unsteady equations for continuity, momentum,...
Background The objective of the present study is to analyse the steady second-order slip flow and heat transfer of an incompressible viscous water-based nanofluid over a stretching/shrinking sheet both analytically and numerically. Methods Using the scaling group transformations, a system of partial differential equations governing the flow and thermal fields is transformed into a system of ordinary...
In this paper we analyzed the effects of space and temperature dependent internal heat generation/absorption (non-uniform heat source/sink) on magnetohydrodynamic boundary layer flow of water based nanofluid over a stretching sheet with different nanoparticles. The flow is generated due to linear stretching of the sheet and influenced by uniform magnetic field, which is applied normally to the stretching...
