Effects of the Control Parameters on the Stability of a Laminar Boundary Layer on a Porous Flat Plate

Abstract This work is devoted to the analysis of linear temporal stability a laminar dynamic boundary layer on horizontal porous plane plate. The basic flow assumed be and two-dimensional. velocity profiles are obtained by numerically solving Blasius equation using Runge-Kutta method. perturbations these solutions expressed in form three-dimensional Tollmien-Schlichting waves. formulation problem leads Orr-Sommerfeld modified permeability parameter (Darcy number) small Reynolds number. given general which can applied Chebyshev domain solved spectral collocation marginal diagrams, critical numbers eigenvalue spectra for different values parameters have equation. Numerical indicate importance effect characteristics.
