Modelling of Stagnation-Point Flow and Diffusion of Chemically Reactive Species Past A Permeable Quadratically Stretching/Shrinking Sheet
نویسنده
چکیده
A numerical study has been conducted to investigate the modelling of steady two-dimensional stagnation-point flow and diffusion of chemically reactive species of a viscous and incompressible fluid past a permeable quadratically stretching/ shrinking sheet. Similarity transformation has been used to reduce the governing nonlinear partial differential equations into a system of nonlinear ordinary differential equations. The resulting equations are solved numerically using “bvp4c” function in MATLAB. Dual solutions are found for a certain range of the stretching/shrinking parameter. The effects of the governing parameters on the skin friction coefficient and the concentration gradient are discussed and illustrated graphically. Keywords-stagnation-point flow; diffusion; chemically reactive species; stretching/shrinking sheet; dual solutions

متن کاملNon-alignment stagnation-point flow of a nanofluid past a permeable stretching/shrinking sheet: Buongiorno’s model
The paper deals with a stagnation-point boundary layer flow towards a permeable stretching/shrinking sheet in a nanofluid where the flow and the sheet are not aligned. We used the Buongiorno model that is based on the Brownian diffusion and thermophoresis to describe the nanofluid in this problem. The main purpose of the present paper is to examine whether the non-alignment function has the eff...

متن کاملThe Magnetohydrodynamic Stagnation Point Flow of a Nanofluid over a Stretching/Shrinking Sheet with Suction
The magnetohydrodynamic (MHD) stagnation point flow of a nanofluid over a permeable stretching/shrinking sheet is studied. Numerical results are obtained using boundary value problem solver bvp4c in MATLAB for several values of parameters. The numerical results show that dual solutions exist for the shrinking case, while for the stretching case, the solution is unique. A stability analysis is p...
