MHD Stagnation Point Flow of Hyperbolic Tangent Fluid With Viscous Dissipation and Chemical Reaction

Abstract

In the present work, two dimensional flow of a hyperbolic tangent fluid with chemical reaction and viscous dissipation near a stagnation point is discussed numerically. The analysis is performed in the presence of magnetic field. The governing partial differential equations are converted into non-linear ordinary differential equations by using appropriate transformation. The resulting higher order non-linear ordinary differential equations are discretized by finite difference method and then solved by SOR (Successive over Relaxation parameter) method. The impact of the relevant parameters is scrutinized by plotting graphs and discussed in details. The main conclusion is that the large value of magnetic field parameter and wiessenberg numbers decrease the streamwise and normal velocity while increase the temperature distribution. Also higher value of the Eckert number Ec results in increases in temperature profile.

MHD Thermal and Solutal Stratified Stagnation Flow of Tangent Hyperbolic Fluid Induced by Stretching Cylinder with Dual Convection

“…When there are two separate layers in a pore media, Adigun et al [9] studied the slip-flow of viscoelastic nanomaterials close to the stagnation point in the appearance of MHD across an angled stretched cylindrical surface. MHD flow of a fluid (hyperbolic tangent) at its stagnation point was explained by Arshad and Ashraf [10] using viscous dissipation and chemical reaction. By combining the consequences of Soret and Dufour, Ali et al [11] examined the 3D flow of MHD hyperbolic tangent nano liquid in the form of a convective stretched sheet.…”
