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.

“…Jeffrey fluid is one of non-Newtonian fluid because of the rheological behavior that related to the stress and strain rate. It is classified as shear thinning fluid which exhibits infinite viscosity at zero strain rate, no flow occurs when the stress applied is lower than yield stress, and zero viscosity at infinite strain rate [12]. Jeffrey fluid model is a simple linear model which employed time derivatives instead of convective derivatives.…”

The numerical study is presented for the magnetohydrodynamic (MHD) squeezing flow of Jeffrey fluid between two parallel plates in a porous medium with the presence of thermal radiation, heat generation/absorption and chemical reaction. The effect of joule heating and viscous dissipation are also examined. Similarity transformation is implemented to transform the governing nonlinear partial differential equations into the system of ordinary differential equations. The resulting equations are solved via numerical scheme of Keller-box method. The accuracy of the present results is validated by comparing the skin friction coefficient, Nusselt and Sherwood numbers with previous published works. The results are noticed in good agreement. Findings reveal that fluid velocity and wall shear stress accelerate when the plate is squeezed. Also, the fluid velocity, temperature and concentration reduce with increase in ratio of relaxation to retardation times and Hartmann number. The increment of viscous dissipation and heat source/sink boost the fluid temperature and the rate of heat transfer. Meanwhile, the presence of thermal radiation decreases the fluid temperature and increases the rate of heat transfer. Further, the rate of mass transfer elevates in the destructive chemical reaction and reverse effect is shown in the convective chemical reaction.

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.
