Abstract: Motivated by one open problem in the classical book “Mathematical models in Boundary Layer Theory” by O.A. Oleinik V.N. Samokhin. We consider the boundary layer theory in Magneto Hydrodynamics. The solvability of MHD boundary layer equations the validity of Prandtl boundary layer ansatz for MHD equations are studied in Sobolev spaces. Compared with the well-posedness theory of the classical Prandtl equations for which the monotonicity condition of the tangential velocity plays a crucial role, this monotonicity condition is not needed for MHD boundary layer any more. Moreover, the validity of Prandtl boundary layer ansatz for MHD is also achieved in Sobolev spaces for some physical parameter regime.
