Boundary Layer Flows Over Sharp and Spherically Blunted Cones at Angle of Attack to Supersonic Nonuniform Free Streams. Volume I. Analysis and Results.

Abstract

Methods have been developed to solve the problem of laminar boundary layers on sharp and spherically blunt cones at angle of attack to nonuniform supersonic free streams. A three-dimensional boundary-layer solution is used to solve sharp cone problems and the afterbody of blunt cone problems. An axisymmetric boundary-layer solution is used to solve the axisymmetric region of blunt cones. An existing implicit finite-difference numerical scheme was used to solve both the axisymmetric and three-dimensional boundary-layer equations. A modified inverse method for solving the inviscid flow field is used to provide edge properties for the axisymmetric region of blunt cones. Normalized skin friction and heat transfer coefficients for a sharp cone in two-dimensional shear flow increase downstream relative to conical flow values. (Modified author abstract)
