Hydromagnetic flow over a surface stretching with a power-law velocity. (English) Zbl 0899.76375

Summary: The boundary layer flow due to a plate stretching with a power-law velocity distribution in the presence of a transverse magnetic field is studied. A special form of the magnetic field is chosen so as to yield similarity equations. First, linearized solutions for the case of large magnetic parameters are presented. Then, an accurate expression for the skin friction coefficient is derived using Crocco’s transformation. This is followed by a direct numerical solution of the resulting boundary value problem using a shooting method.
