MHD TURBULENT FLOW IN PRESENCE OF INCLINED MAGNETIC FIELD PAST A ROTATING SEMI-INFINITE PLATE

Abstract

A turbulent incompressible fluid flow past a semi-infinite vertical rotating plate has been investigated, the flow considered is in the presence of a strong inclined constant magnetic field. An induced electric current exists due to the presence of the constant magnetic field. The velocity distribution of the fluid flow past a semi-infinite vertical plate and it's temperature profiles have been determined. Finally, the effects of various parameters like non-dimensional numbers and the angle of inclination of the magnetic field on the flow variables have been determined. The equations governing this problem have been solved numerically using finite difference method because these equations are non-linear and there exists no analytical method of solving them. A sample result of the velocity profiles and temperature profiles have been obtained followed by a graphical representation of the same. It is noted that an increase in the Hall parameter, time and angle of inclination leads to an increase in the primary velocity while an increase in the rotational parameter Er and Eckert number leads to a decrease in the primary velocity profiles. An increase in the rotational parameter and Hall parameter leads to an increase in secondary velocity, Eckert number, time and angle of inclination leads to a decrease in secondary velocity. Increase in Eckert number, time, Hall parameter and rotational parameter leads to an increase in temperature profiles.
