INVESTIGATION OF HEAT TRANSFER AND SUCTION AS A MEANS FOR TRIPPING THE BOUNDARY LAYER.

Abstract

An experimental investigation was made to determine the feasibility of tripping the laminar boundary layer on an airfoil by means of heat transfer or suction through an isolated hole. The effect of heat transfer on both favorable and adverse pressure gradients was studied. It was found that neither heat transfer nor suction was adequate to precipitate transition within the limits of these experiments for chord Reynolds numbers between 1.6 x 1,000,000 and 2.46 x 1,000,000. The experimental findings were checked by the boundary-layer-stability analysis, and excellent agreement was obtained with experiment. (Author)
