A Correlation of Artificially Induced Boundary-Layer Transition Data from Blunt Slender Cones at Hypersonic Speeds

Abstract

Previous investigations of distributed-roughness boundary-layer trips indicated that they are superior to spherical-type trips in that equally effective distributed-roughness trips are one-fifth as high and produce substantially smaller flow-field disturbances. The present work has expanded the data base, permitting correlation of distributed roughness tripping data. The correlation thus developed includes a wide range of Reynolds numbers, cone angles, and trip heights. Plots are provided that permit the selection of distributed-roughness trips without the need of boundary-layer solutions.
