Moore-Stewartson transformation

Many boundary-layer problems possess similarity solutions—solutions in which appropriately identified dependent variables may be expressed as functions of a single independent variable, t], the nondimensional similarity variable, through functions defined by ordinary differential equations in f/. To facilitate derivations of similarity solutions, after employing the Moore-Stewartson transformation, we shall further transform the equations to a general similarity variable and introduce a nondimensional stream function F(x, t], t), according to...
