Unsteady mixed convection flow through a permeable stretching flat surface with partial slip effects through MHD nanofluid using spectral relaxation method

Abstract

An unsteady, laminar, mixed convective stagnation point nano uid ow through a permeable stretching at surface using internal heat source or sink and partial slip is investigated. The e ects of thermophoresis and Brownian motion parameters are revised on the traditional model of nano uid for which nano uid particle volume fraction is passively controlled on the boundary. Spectral relaxation method is applied here to solve the nondimensional conservation equations. The results show the illustration of the impact of skin friction coe cient, different physical parameters, and the heat transfer rate. The nano uid motion is enhanced with increase in the value of the internal heat sink or source. On the other hand, the rate of heat transfer on the stretching sheet and the skin friction coe cient are reduced by an increase in internal heat generation. This study further shows that the velocity slip increases with decrease in the rate of heat transfer. The outcome results are benchmarked with previously published results.

Fluid properties of an unsteady MHD free stream flow over a stretching sheet in presence of radiation

“…Following studies 12–14 extended this work on heat transfer characteristics over stretching surfaces. The unsteady flow behavior with magnetic field on a stretching and shrinking sheet has been reported by Abel and colleagues 15–19 and Mondal and colleagues, 20–22 respectively with various fluid parameters and distinct physical conditions.…”

Time-Dependent Magnetohydrodynamic (MHD) Flow of an Exothermic Arrhenius Fluid in a Vertical Channel with Convective Boundary Condition

“…As part of a previous study, we solved the governing equations ( 8) and ( 9) at same time with the same boundary condition (10); however, the IFDS approach is used to solve equations ( 5) and ( 6) with relation to the boundary condition (7). Table 1 displays the numerical validation of reference work [29] and present work.…”

“…Gul et al [6] reviewed the MHD combined flow movement in a vertical channel. Using the spectrum relaxation technique, Ahamed et al [7] studied the effects of transient free and forced convection flow on the partial slip effect in MHD nanofluid. In [8,9], one can create excellent mixed convection flow courses.…”

Mixed convection flow of nanofluid with Hall and ion-slip effects using spectral relaxation method

“…Mahanthesh et al [25] numerically investigated the influences of buoyancy force, nanoparticles, chemical reaction, and heat source/sink on combined forced and free convection flow of an electrically conducting water-based Cu-nanofluid past a moving/stationary vertical plate using Laplace transform method. The impacts of different governing parameters on mixed convection flow of nanofluid past stretching surfaces were studied by ( [26][27][28]). Most recently, Khan and Rasheed [29] scrutinized magnetohydrodynamic (MHD) combined natural and forced convection flow of the Maxwell nanofluid with magnetic field and buoyancy force effects.…”
