Abstract:

This report presents a detailed triple-deck theory of the transonic shock-nonseparating turbulent boundary layer interaction zones on spinning axisymmetric bodies at zero angle of attack. The theory allows a general non- equilibrium turbulent boundary layer history upstream of the interaction. We further describe the application of this theory as a local interactive module imbedded in a global composite viscous-inviscid transonic flow field prediction method which can handle two or more such interaction zones. Detailed comparisons with both experimental data and thin-layer Navier-Stokes code predictions are presented to verify the accuracy and reliability of the composite method solutions for pressure, displacement thickness, velocity profiles, shape factor and skin friction distirbutions along the body over a wide range of Mach Reynolds number conditions.
