Mathematic modeling for boundary layer flow over a stretching or shrinking cylinder

In this study, the steady boundary layer flow, mass transfer and heat transfer of a cylinder near the stagnation point over a stretching or shrinking sheet are investigated numerically. The governing nonlinear partial differential equations are transformed into a system of nonlinear ordinary differe...
