Generalized MHD Couette flows in an annuli: the Riemann-sum approximation approach
2022In this study, a mathematical analysis is presented for unsteady MHD generalized Couette flow of an incompressible and electrically conducting fluid in an annulus formed by two concentric cylinders of infinite length. The governing equations are obtained and solved using Laplace transform and the Riemann sum approximation method.
