Numerical study of dispersion of nanoparticles in magnetohydrodynamic liquid with Hall and ion slip currents

Abstract

Heat transfer in partially ionized Erying-Powell liquid containing four types of nano-particles is discussed in this manuscript. Mathematical models for the mixture Erying-Powell plasma and nano-particles are developed and are solved by using finite element method (FEM). Numerical computations are carried out under tolerance 10-5. Physical parameters have significant effects on both thermal boundary layer thicknesses and momentum boundary layer thicknesses. Shear stresses at the surface can be minimized by the Hall and ion slip currents whereas the shear stresses at the sheet for Erying-Powell fluid are high as comparing to the Newtonian fluid. The rate of transfer of heat is significantly influenced by Hall and ion slip parameters. Highest rate of transfer of heat is observed for the case of TiO2 nano-particles. Therefore, it is recommended to disperse TiO2 nano-particles in Erying-Powell fluid for enhancement of heat transfer in Erying-Powell plasma.

Comparative analysis of magnetized partially ionized copper, copper oxide–water and kerosene oil nanofluid flow with Cattaneo–Christov heat flux

“…For the modeling of magnetized partially ionized fluid flow, these forces can be measured by implementing generalized Ohm's law 28 with mass, momentum, energy, and Maxwell equations. Qureshi et al 29 proposed the model of Hall and Ion slip currents-based 3D nano-plasma flow in the presence of thermal radiation. Nazir et al 30 studied the Cu and Ag nanoparticles based partially ionized Casson nanofluid flow with thermal radiation over a stretching surface.…”

Analysis of second law on Eyring‐Powell nanoliquid flow in a vertical microchannel considering magnetic field and convective boundary

“…The dimensionless equations-Equations (7) to (9)-along with Equations (10) and (11) are manipulated by using the RKF45 scheme along with shooting technique. [42][43][44][45] The maximum step size 0.001 is applied to obtain the numerical result. The criteria for convergence is 10 −6 .…”

“…The impact of heat source on stretching surface has been examined by Raju et al 40 considering both the effect of chemical reaction and viscous dissipation. Thermal behavior of Carreau fluid for the impact of heat source has been deliberated by Yousif et al 41 Dispersion of nanoparticles has been investigated by Qureshi et al 42 with the combined effect of Hall and ion factor. They established that heat transfer rate intensified with Hall current.…”

MHD Effects on Ciliary-Induced Peristaltic Flow Coatings with Rheological Hybrid Nanofluid

“…Hybrid nanofluids can be manufactured by dispersing nanoparticles of different materials individually or a mixture of nanoparticles in base fluid. For instance, impacts of Cu-Ag nanohybrids on velocity and thermal boundary layer transport inside the wedge have been investigated by Hassan et al [6]. To gain the highest composite thermal conductivity, chemical inertness and stability by using a small-volume fraction of nanoparticles at lower production cost is the motivation of researchers behind their utilization of hybrid nanofluids [7][8][9][10].…”
