Abstract

In the present communication, it is shown for the first time that in a discharged jet over a plane surface in the presence of a transverse magnetic field, there exists a critical coordinate in which the shear stress at the wall becomes zero; afterward, it is expected a region of reversed flow and hence, an altered flow dynamic. This coordinate was noticed by the numerical solution of the perturbed-differential transformation of the governing equations using Runge–Kutta–Fehlberg (RKF45). It is argued that in the flow control applications regarding the magnetohydrodynamic wall jet, this newly found critical coordinate should be put into considerations for an optimal design.
