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
