Stagnation flow of hybrid nanoparticles with MHD and slip effects

Abstract

The flow of hybrid nanoparticles with significant physical parameters with different base fluids in the presence of Biot number, velocity slip, and MHD effects has not been explored so far, particularly for a circular cylinder. Therefore, the current report is presented to offer a numerical solution for hybrid nanoparticles with base fluids (water and ethylene glycerol) via a circular cylinder. The physical situation is interpreted in terms of partial differential equations and is converted into ordinary differential equations after applying the similarity transformation. The results are presented in both tabular and graphical forms. The impact of physical parameters on velocity distribution is examined through graphs. The comparative results of hybrid nanoparticles for distinct base fluids as ethylene glycol and water are proposed and the hybrid nanoparticles with base fluid water seems to be greater than that of the hybrid nanoparticles with base fluid EG. The temperature profile of hybrid nanoparticles is found to be a decreasing function with growth in velocity slip parameter γ but an opposite trend is noted in case of nanoparticles Φ 2 . The skin friction and Nusselt number augmented for the increase in magnetic field, velocity slip, and nanoparticle while it shows a decreasing trend toward thermal slip parameter. For the both cases, improvement in Biot number helps enhance the heat transfer constantly. K E Y W O R D S circular cylinder, hybrid nanoparticles, MHD, slip conditions, water and ethylene glycol

Magnetohydrodynamics unsteady separated stagnation‐point (USSP) flow of a hybrid nanofluid on a moving plate

“…Most review studies also ascertained that the hybrid nanofluid contributes to an extra thermal conductivity as compared to the single nanofluid [22][23][24]. Besides, few researchers also have actively investigated the hybrid nanofluid with various flow geometries either on the steady or unsteady flow [25][26][27][28][29][30].…”

Impact of Maxwell velocity slip and Smoluchowski temperature slip on CNTs with modified Fourier theory: Reiner-Philippoff model

“…Raza et al [ 38 ] investigated thermal radiation and slip velocity effects concurrently with a heated convective stretching plate. Abbas et al [ 39 ] exhibited the flow of hybrid nanoparticles with slip velocity and MHD. In the presence of thermal and hydrodynamic slip conditions, Rao et al [ 40 ] proposed the laminar free convective boundary-layer flow of a Casson viscoelastic fluid external to a vertical permeable spherical cone.…”

Entropy generation minimization and nonlinear heat transport in MHD flow of a couple stress nanofluid through an inclined permeable channel with a porous medium, thermal radiation and slip

“…In this context, studies of fluids with slip velocity effect find applications in some systems with fluids where the ratio between the surface and volume is large. [9][10][11][12][13] For instance, Ramesh et al 14 investigated the radiation and Joule heating effects on magnetohydrodynamic (MHD) Carreau fluid with hydrodynamic slip, and in another study, 15 analyzed the effects of slip and Hall current on Jeffrey fluid suspension flow in a peristaltic MHD blood micropump. These slip effects together with entropy production analysis were considered in systems with and without applied external field.…”

“…Similar studies were conducted by Mahian et al 8 where a review of the related studies to the entropy production in nanofluids was shown. In this context, studies of fluids with slip velocity effect find applications in some systems with fluids where the ratio between the surface and volume is large 9‐13 . For instance, Ramesh et al 14 investigated the radiation and Joule heating effects on magnetohydrodynamic (MHD) Carreau fluid with hydrodynamic slip, and in another study, 15 analyzed the effects of slip and Hall current on Jeffrey fluid suspension flow in a peristaltic MHD blood micropump.…”
