Abstract:The unsteady viscous incompressible stagnation point flow over an expanding/contracting cylinder with heat and mass transfer is studied in this article. The governing partial differential equations are transformed into a couple nonlinear ordinary differential equations by using similarity transformation. These obtained nonlinear ordinary differential equations are solved numerically by using spectral method. There exist unique, dual, and triple solutions in the presence of unsteadiness parameter S for differen… Show more
In this article, a numerical study is carried out for the steady two-dimensional flow of an incompressible Maxwell fluid in the region of oblique stagnation point over a stretching sheet. The governing equations are transformed to dimensionless boundary layer equations. After some manipulation a system of ordinary differential equations is obtained, which is solved by using parallel shooting method. A comparison with the previous studies is made to show the accuracy of our results. The effects of involving parameters are discussed in detail and the streamlines are drawn to predict the flow pattern of the fluid. It is observed that increasing velocities ratio parameter (ratio of straining to stretching velocity) helps to decrease the boundary layer thickness. Furthermore, the velocity of fluid increases by increasing the obliqueness parameter.
