The heat and mass transfer on time dependent hydrodynamic squeeze flow of Jeffrey nanofluid across two plates over permeable medium in the slip condition with heat generation/absorption, thermal radiation and chemical reaction are investigated. The impacts of Brownian motion and thermophoresis is examined in the Buongiorno’s nanofluid model. Conversion of the governing partial differential equations to the ordinary differential equations is conducted via similarity transformation. The dimensionless equations are solved by imposing numerical method of Keller-box. The outputs are compared with previous reported works in the journals for the validation of the present outputs and found in proper agreement. The behavior of velocity, temperature, and nanoparticles concentration profiles by varying the pertinent parameters are examined. Findings portray that the acceleration of the velocity profile and the wall shear stress is due to the squeezing of plates. Furthermore, the velocity, temperature and concentration profile decline with boost in Hartmann number and ratio of relaxation to retardation times. It is discovered that the rate of heat transfer and temperature profile increase when viscous dissipation, thermophoresis and heat source/sink rises. In contrast, the increment of thermal radiation reduces the temperature and enhances the heat transfer rate. Besides, the mass transfer rate decelerates for increasing Brownian motion in nanofluid, while it elevates when chemical reaction and thermophoresis increases.

The present study explores the influences of chemical reaction and viscous dissipation on the hydromagnetic squeeze flow of Jeffrey fluid in channel over porous medium by slip boundary. The nonlinear partial differential equations are converted to the nonlinear ordinary differential equations using dimensionless variables and solved through numerical approach of Keller-box. The results of skin friction coefficient, Nusselt and Sherwood numbers are compared with existing results in the journal for validation of the present results. Comparison shows that the numerical outputs are in excellent agreement. Findings indicate that wall shear stress and fluid velocity increase as the plates approaching each other. Also, increment of Hartmann number (from 0.5 to 6.5) and ratio of relaxation and retardation times decrease the velocity, temperature and concentration profile. The effect of viscous dissipation elevates the heat transfer rate and temperature profile. Besides, mass transfer rate drops in convective chemical reaction and opposite impact is noticed in destructive chemical reaction.

“…The significance of the researches on the non-Newtonian flow has been acknowledged by scientists due to its implementation on engineering industries. Casson fluid is known as shear thinning flow because of high yield stress and shear viscosity [8]. Commonly, the fluid acting as solid, but it starts to flow if the strong force is imposed on the fluid.…”

Ultrahigh-performance cooling is one of the essential requirements in the industrial technology. Hence, the new heat transfer fluid, hybrid nanofluid is introduced to increase the thermal conductivity of fluid and investigated with various physical parameters. The unsteady magnetohydrodynamics (MHD) flow of Casson hybrid nanofluid through two surfaces in a permeable medium with chemical reaction are explored. The hybrid nanoparticles of Alumina and Copper is dispersed in the base fluid of sodium alginate . The discretize equations are solved using similarity transformation and Keller-box methods. The comparison of the current results with the published results for validation is conducted and discovered in proper agreement. The impacts of squeeze, magnetic, porous media, chemical reaction, heat sink/source, and Soret and Dufour on behaviour and physical quantities of flow are discussed. The graphical results show the squeeze of two surfaces accelerates the fluid velocity near the upper plate region. Further, the velocity slowing down when and increases, and it elevates as and rises in the middle of channel. The increment of heat transfer rate and temperature of fluid is shown for increasing Ec, y and Du, and the opposite behaviour is discovered with raise in. The fluid concentration decreases and the mass transfer rate enhances for rising Sr. The concentration enhance and rate of mass transfer reduce with the constructive chemical reaction, whereas contrary effects is shown for destructive chemical reaction.
