Theoretical study of unsteady oblique stagnation point based Jeffrey nanofluid flow over an oscillatory stretching sheet

The numerical analysis for two-dimensional oblique stagnation point flow with the magnetohydrodynamic effects of an incompressible unsteady Jeffrey fluid model caused by an oscillatory and stretching sheet has been presented in this article. The Brownian motion and thermophoresis impacts are taken into consideration. The similarity transformation technique is implemented on the governing partial differential equations of the Jeffrey fluid model to obtain a set of nonlinear coupled ordinary differential equations and then these resulting equations are numerically computed with the help of BVP-Maple programming. The variation in the behavior of velocity, temperature, and concentration profile influenced by the governing parameters, has been explicitly explored and displayed through graphs. The numerical results are highlighted in tabular form and through these outcomes, the skin friction coefficient, Nusselt number, and Sherwood number have been investigated. These physical quantities rise for gradually increasing the Hartmann number and ratio of relaxation to retardation time. However, these reduce for gradually growing Jeffrey fluid parameter.

Soret and dufour effects on hydromagnetic flow of Eyring-Powell fluid over oscillatory stretching surface with heat generation/absorption and chemical reaction

In this article, we have investigated thermal-diffusion and diffusion-thermo effects on unsteady flow of electrically conducting Eyring-Powell fluid over an oscillatory stretching sheet by using convective boundary conditions. A set of appropriate variables are used to reduce number of independent variables in governing equations. Series solution is computed using homotopy analysis method. The effects of various parameters of interest on the velocity filed, temperature profile, concentration profile, skin friction, local Nusselt number and local Sherwood number are illustrated graphically and discussed in detail.

Hydromagnetic Flow and Heat Transfer of a Jeffrey Fluid over an Oscillatory Stretching Surface

The flow and heat transfer of a Jeffrey fluid over an oscillatory stretching sheet is investigated using the boundary-layer approximations. The flow is induced due to infinite elastic sheet that is stretched periodically. The number of independent variables in the governing equations was reduced by using appropriate dimensionless variables. This dimensionless system has been solved by using the homotopy analysis method (HAM) and a finite difference scheme, in which a coordinate transformation was used to transform the semi-infinite physical space to a bounded computational domain. A comparison of both solutions is provided. The effects of involved parameters are illustrated through graphs and discussed in detail.
