A transformation is derived from first principles to reduce the boundary-layer equations for a general compressible two-dimensional flow to incompressible form. For the case of boundary-layer flow of a Newtonian fluid past a smooth wall, but with no other restrictions, it is shown that the combination (rho[infinity]µ[infinity]/rhowµw) CfRetheta is an invariant of the transformation.   Direct numerical simulation of a spatially developing supersonic mixing layer with a convective Mach number of is conducted. The present work focuses on the structural evolution and the turbulent statistics, and both instantaneous and time-averaged data are utilized to obtain further insight into the dynamical behaviors of the by: 4.

A modified Reynolds analogy is developed for the compressible turbulent boundary layer on a flat plate. When mixing-length theories are used to evaluate terms of the final expressions, it is found for air that the ratio of Stanton number to half the local skin-friction coefficient is greater than unity. The effects of streamwise adverse and favorable pressure gradients on turbulent boundary layer flow characteristics (velocity profiles, turbulence and skin friction) and vortex formation over a flat plate with riblets at low speed (U = 5 m/s) were studied. Normal and spanwise velocity profiles for both pressure gradients showed the presence of Author: Franklin L. Dement.   Numerical investigation of the compressible flow past an 18% thick circular-arc aerofoil was carried out using detached-eddy simulation for a free-stream Mach number M ∞ = and a Reynolds number Re = × 10 s have been validated carefully against experimental by:

The generation of a turbulent inflow for the numerical simulation of a boundary layer is in itself an issue, owing to the difficulty of obtaining a physical turbulent flow at a rea-sonable computational cost. Different approaches, including temporal boundary layer TDNS, extended TDNS, and spa-tial boundary layer, have been developed. In the.

The difficulty behind measuring both variables independently is due to a coupling effect that occurs at high speeds. Once the Mach number exceeds approximately , compressibility effects in .
