Turbulent Boundary-Layer Separation

This article summarizes our present understanding of the physical behavior of two-dimensional turbulent separated flows, which occur due to adverse pressure gradients around streamlined and bluff bodies. The physical behavior of turbulence is flow dependent, so detailed experimental infor­ mation is needed for understanding such flows and modeling their physics for calculation methods. An earli...

Turbulent boundary layer equations

We study a boundary layer problem for the Navier-Stokes-alpha model obtaining a generalization of the Prandtl equations conjectured to represent the averaged flow in a turbulent boundary layer. We solve the equations for the semi-infinite plate, both theoretically and numerically. The latter solutions agree with some experimental data in the turbulent boundary layer.

Multi-fidelity numerical simulations of shock/turbulent-boundary-layer interaction in a duct with uncertainty quantification

The interaction between shock waves and turbulent boundary layers (STBLI) plays a fundamental role in the operation of (sc)ramjet engines utilized in supersonic/hypersonic flight vehicles. In particular, the isolator part of such engines is often designed to contain a series of shock waves (shock-train) that sets the flow of incoming, atmospheric air in the optimal conditions for its subsequent...
