Abstract
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.
