In this study, the magnetohydrodynamic flow of an incompressible, viscous electrically conducting fluid through a convergent-divergent channel in the presence of an oblique variable magnetic field to the flow with a case of suction and injection on the walls has been investigated. The velocity profiles, temperature profiles, the effects of injection and suction, time, induced magnetic field and the effects of varying various parameters on the flow have been investigated. The equations governing the MHD flow are solved by the collocation method and the results presented in graphs. The velocity, temperature, and magnetic induction increases with the increase in the suction parameter and decrease in the wedge angle while velocity, temperature, and magnetic induction reduce with the increase in the injection parameter. The velocity, temperature and magnetic induction increase with the increase in the Hartmann number. The results of this study will be useful information to the engineers to improve the performance and efficiency of machines in the industrial, environmental, aerospace, chemical, civil, mechanical and biomechanical engineering applications.
