HYPERSONIC VISCOUS INTERACTION THEORY FOR SLENDER AXISYMMETRIC BODIES,
Abstract
Effects of viscous interaction are investigated for hypersonic flow over slender axisymmetric bodies. The entire range of interaction, from weak to strong, is considered for nose bluntness not greater than a 3/4 power law. Extensive numerical results are given for the self-similar flow over a 3/4 power law body. These results are correlated and used in a local similarity procedure for finding viscous interaction over arbitrary body shapes. Analytical expressions are derived for weak interaction on a cone and strong interaction on power law bodies. Following Dewey's approach, the local similarity procedure is simplified to a series of algebraic equations. These are solved for flow of air over a cone. Numerical results are presented for cone surface pressure, shear, heat transfer, drag and displacement thickness in all interaction regimes. The drag is in good average agreement with available experimental cone drag data. The analytical development is a unified treatment of viscous interaction effects on two-dimensional as well as axisymmetric bodies. Numerical results for wedges are included. (Author)
