<p>This study utilizes a robust MHD solver, ANUPRAVAHA, to numerically analyze the influence of dimensional parameters in a disaligned channel. We focused on the impact of key dimensional parameters, the height of the disaligned section (D), the thickness of the channel (T), and the channel width (W). The influence of these parameters on pressure distribution, velocity profiles, and electric potential are systematically studied. The results show that increasing the height of the disaligned section, channel thickness, or width leads to a decrease in maximum outlet velocity and a reduction in pressure drop, although the effects vary in magnitude. When D increases from 1 to 3, peak outlet velocity rises by 8.18% while pressure drop falls by 13.60%. Increasing T from 1 to 3 boosts peak velocity by 7.91% and reduces pressure drop by 44.80%. Increasing the width from W = 1 to W = 3 leads to 6.60% increase in velocity and a 41.60% decrease in pressure drop. Increasing the disaligned section height (D) and channel thickness (T) elevates flow resistance and recirculation zones, while increasing the width of the channel mainly increases the separation zones, core velocity, and energy dissipation. It is also observed that an increase in these parameters uniformizes the pressure gradient. The effect of the dimensional parameters on circulation zones and flow separation is also observed. It is found that the thickness of the channel increases boundary layer thickness, the height of the disaligned section elongates the flow pattern, and the width widens the separation zone.</p>
