Popis:	Magnetohydrodynamics has been one of the promising ways of increasing efficiency of supersonic as well as hypersonic propulsion systems, mostly by applying magnetic fields over shockwaves. This paper presents the effects of magnetic fields with different strengths both along and transverse to an electrically conducting flow at Mach 2.94 over a blunt body using a density-based solver implemented with MHD equations in OpenFOAM. The solver utilises Riemann method with an AUSM+ flux splitting technique along with limited linear interpolation. The effects of imposed magnetic field on temperature and shock standoff distance are observed. Movement of the shockwave due to the application of magnetic field on the geometry, along with a consequent change in shock standoff distance is presented in the paper. The influence of a magnetic field's direction on the Mach number of the flow is also shown. Likewise, the stagnation temperature of the blunt body is demonstrated to be independent to the direction of applied magnetic field.
