Calculation of compressible adiabatic turbulent boundary layers
TLDR
In this article, a method of solution of the compressible turbulent boundary-layer equations for twodimensional and axisymmetric flows, with transverse-curvature effects, is presented.Abstract:
A method of solution of the compressible turbulent boundary-layer equations for twodimensional and axisymmetric flows, with transverse-curvature effects, is presented. The Reynolds shear-stress term is eliminated by an eddy-viscosity concept and the time mean of the product of a fluctuating velocity and temperature term appearing in the energy equation is eliminated by an eddy-conductivity concept. An implicit finite-difference method is used in the solution of both momentum and energy equations after they are linearized. Results are presented for several adiabatic compressible flows, with and without pressure gradients for Mach numbers up to 5. The results show that the method is quite accurate and fast; a typical flow can be calculated in one or two minutes on the IBM 360/65 computer.read more

Calculation of boundary-layer development using the turbulent energy equation: compressible flow on adiabatic walls
P. Bradshaw,D. H. Ferriss +1 more
TL;DR: In this article, the basic method described by Bradshaw, Ferriss & Atwell (1967) is extended to compressible flow in two-dimensional boundary layers in arbitrary pressure gradient (without shock waves and expansion fans) by invoking Morkovin's hypothesis (Favre 1964) that the turbulence structure is unaffected by compressibility.

Unsteady Viscous Flow on Oscillating Airfoils
W. J. Mccroskey,J.J. Philippe +1 more
TL;DR: In this article, the importance of unsteady effects on laminar boundary layers was found to diminish rapidly with increasing longitudinal pressure gradients, whereas turbulent separation on airfoils was significantly affected by oscillatory motion when the incidence approached the stall angle.
