Micropolar flow past a porous stretching sheet. (English) Zbl 0589.76017
Summary: The flow of an incompressible, constant density micropolar fluid past a porous stretching sheet is investigated. The governing boundary layer equations are transformed into a numerically equivalent system of nonlinear ordinary differential equations. The resulting equations are solved numerically using a globally convergent homotopy method in conjunction with a least change secant update quasi-Newtonian algorithm. The flow pattern depends on three nondimensional parameters and a suction (or injection) parameter A. A comparison between the \(A=0\) flow behavior representing an impermeable sheet and fluid flow behavior for the porous sheet (A\(\neq 0)\) is presented with the numerical results illustrated graphically.
