Abstract:
In this thesis, stability analysis of incompressible laminar boundary layer flow is
presented in detail for various test cases, For this approach, the partial differential
equallon is converted into ordinary differential equation by suitable approximation. Then
by using implicit finite difference scheme to find the point of separations of the boundary
layer equallons. The fmite difference equations for the given flo,", at each longitudinal
position form a linear set with a In diagonal coefficient matrix. To ensure the correCI
results, above method is checked with standard flows like flow past circular cylinder,
Howarth's linear decelerating flows. These methods are demonstrated to compute
accurately the separation points of several flows for which comparisons the outcomes of
this work with prcvlOusly published results are possible. Then variOl.lsseries are tested
WIth complller codes. At last the stability diagram for plane pOiseuille flow is also shown.
