BLASIUS EQUATION Solution with Finite Difference Method

  1. Nov 18, 2007 #1
    1) Using a similarity variable, the boundary layer equations for a two-dimensional, incompressible flow over a flat plate can be written below:

    2f'''+ff''=0


    The boundary conditions are:

    a) f ' (0) = 0, no slip at the wall
    b) f(0)=0, solid wall
    c) f ' (n) goes 1 as n goes infinity boundary layer solution merges into the inviscid solution.

    I) using finite difference method, obtain a numerical solution of this equation. Plot f ' and f as a function n.
    II) The shear stress on the wall requires f " (0) to be determined. From the numerical solution compute f " (0).
