The compressible Navier-Stokes equations are solved for turbulent spots at Mach 3 and 6, with both adiabatic and cold (T_w = T_∞) wall boundary conditions on a flat plate. From the results turbulent spot growth and propagation rates are derived which will help to quantify the length of laminar to turbulent transition. The simulations also yield skin-friction and heat-transfer data.
