Calculation of laminar boundary layer by integral method for two-fluids upon flat plate

Abstract

In this paper, calculation is done by momentum integral method and based on two-fluids boundary layer. The integral method is an approximate method which can reduce the mathematical difficulties in solving the Navier-Stokes equations in two dimensions. The calculation will be done in MathCAD and Matlab, with the results we figure out that the two-fluids boundary layer has smaller drag than that in general case.
