The Effects of Wall Temperature and Suction on Laminar Boundary-Layer Stability

Abstract

An integral solution of the two-dimensional boundary-layer equations for water with pressure gradient, heat transfer, and suction was employed to investigate laminar boundary-layer stability. It was shown that the effects of suction, wall heating, and pressure gradient on critical Reynolds numbers could be correlated as a function of universal boundary-layer parameters. It was indicated that suction is the most effective and pressure gradient the least effective means to stabilize a boundary layer. However, the effectiveness of suction is enhanced by a favorable pressure gradient.
