Numerical Investigation of Pressure Drops and MHD Flow Through Sudden Expansion in the Presence of an Inclined Magnetic Field

The present study focuses on the numerical investigation of the effect of an incline magnetic field on the behavior of magnetohydrodynamics (MHD) flow in a sudden expansion channel using the Anupravaha CFD solver. The numerical simulations were conducted at various Reynolds numbers (Re = 50–200) and Hartman numbers (Ha = 0–20) for seven different inclinations of the applied magnetic field from 0° to 90°. The results show that the flow behavior is affected by changing the magnetic field's inclination, and the highest-pressure drop is seen at 90° for Re = 100 and Ha = 20. The pressure drop increases with an increase in Hartmann number, and it decreases with increasing Reynolds number.
