Non-isothermal magnetohydrodynamic fluid flow along the centerline in a rotating curved square duct with Hall and ion-slip current

This study is considered a fully developed non-isothermal, viscous, incompressible fluid flow that passes through the centerline of rotating square curved duct in presence magnetic field with Hall and ion-slip current. non-isothermal generated by keeping heat on outer wall cool inner wall; upper lower walls are taken as adiabatic. The aspect ratio l = 1 so cross section viewed square. gravitational force acts an external force, pressure gradient (namely, Dean number effects) has been applied along duct. Due to rotation system curvature, influenced centrifugal Coriolis forces. calculations carried out spectral method primary tool, while Chebyshev polynomial, collocation method, Newton–Raphson arc-length used secondary tools. focus show effects parameter (M), (m), (α) characteristics this rotationally new findings have shown various values M, m, α for three cases numbers, such case I: Dn 1000, II: 3000, III: 5000, different curvatures, rotational fixed at Tr 20. Here, it Dn, Gr, Tr, varied, curvature δ ranges from 0.01 0.5.
