Hermite-Padé approximation approach to MHD Jeffery-Hamel flows. (English) Zbl 1102.76049

Summary: We study the nonlinear flow of incompressible conducting viscous fluid in convergent-divergent channels under the influence of externally applied homogeneous magnetic field. The governing equations are obtained and solved using a special type of Hermite-Padé approximation semi-numerical approach. This technique offers some advantages over solutions obtained by using traditional methods such as finite differences, spectral method, shooting method, etc. It reveals the analytical structure of the solution and important properties of overall flow structure, including velocity field, flow reversal control and bifurcations.
