INFLUENCE OF SURFACE MASS TRANSFER ON THE STABILITY OF FORCED CONVECTION FLOW OVER A HORIZONTAL FLAT PLATE
RESUMO
The effects of suction or blowing surface mass transfer on the stability of two-dimensional laminar forced convection flow over a horizontal flat plate are studied numerically by using temporal linear stability analysis. The mean flow is assumed similar, two-dimensional laminar boundary layer. The mean velocity profiles are obtained numerically for the case of suction and blowing. The flow disturbance modes are governed by the Orr-Sommerfeld equation. This equation is solved numerically by using the Chebyshev spectral collocation method, which is based on the eigenfunction expansion in terms of Chebyshev polynomials, collocation points, and the subsequent solution of the resulting generalized eigenvalue problem with the QZ algorithm. The obtained numerical results are validated by comparison with some previous works. The stability curves, critical Reynolds numbers, eigenvalue spectrum, and eigenfunctions are presented for a range of wall stream function values.
