TENTATIVE GENERALIZATION OF LEADING-EDGE VISCOUS INTERACTION PHENOMENA,

Abstract

The pressure induced by the interaction of a viscous boundary layer with an external hypersonic flow on sharp leading-edge surfaces is a function of three independent parameters. These represent the pressure-deflection sensitivity of the external flow field (interaction parameter), the length scale for the establishment of a boundary layer (rarefaction parameter), and the effect of heat transfer on its rate of growth (wall temperature ratio). An isobar map of the interaction problem in the domain of these independent variables is suggested and explored by using the existing data. This representation provides a framework within which to study further leading-edge interaction phenomena and also discloses contradictions and insufficiencies in the currently available data.
