Numerical Simulation of Hypersonic Boundary Layer Receptivity, Transient Growth and Transition With Surface Roughness

Book Description
The objective of this research is to conduct DNS studies of hypersonic boundary layer receptivity, transient growth and transition with surface roughness. The main approach is to use DNS as a research tool to study the boundary layer receptivity and transient-growth mechanisms in hypersonic flows, including the development of numerical algorithms and parallel computer codes of higher order numerical methods for the simulation of hypersonic flows with surface roughness of finite heights. During the three-year period, we have conducted DNS studies on the hypersonic boundary layer flows over flat plates and blunt cones. A new high-order cut-cell method has been developed for the numerical simulation of hypersonic boundary layer transition with finite height surface roughness. The method has been applied to the numerical simulations of two-dimensional hypersonic flows over a flat plate. Furthermore, the stabilization effect of the surface porous coating over a flat plate is extensively studied by series of numerical simulations. We also collaborate with Prof. Tumin in the University of Arizona to compare numerical and theoretical results on receptivity of a Mach 5.92 flow over a flat plate to wall blowing-suction, and to analyze the nonparallel flow effect.
Studies of the Structure of Attached and Separated Regions of Viscous/Inviscid Interaction and the Effects of Combined Surface Roughness and Blowing in High Reynolds Number Hypersonic Flows

Book Description
The first of these 2 studies examined the detailed structure of the hypersonic boundary layer over a large cone/flare configuration. Emphasis was on development and use of instrumentation with which to obtain flow field measurements of the mean and fluctuating properties of the attached and separated shear layers. Development and use of holographic interferometry and electron beam techniques in the high Mach number and Reynolds number environment developed in the shock tunnel are described. In the second study, detailed measurements of heat transfer, pressure and skin friction were made on a unique 'blowing and roughness' model constructed to simulate the aerothermal phenomena associated with a rough ablating maneuverable reentry vehicle. In the 2nd study emphasis was placed on development and use of unique heat transfer and skin friction instrumentation to obtain measurements of the combined effects of blowing and roughness and to understand how such effects influence boundary layer separation in regions of shock wave/boundary layer interaction. Each focused around providing information with which to construct and evaluate the modeling required in time-averaged Navier-Stokes equations to predict the structure of compressible hypersonic boundary layers in regions of strong pressure gradient, shock wave/boundary layer interaction and flow separation over smooth, rough and ablating surfaces.

The Hypersonic Boundary Layer on a Wedge with Uniform Mass Addition and Viscous Interaction

Book Description
The effects of uniform surface blowing on the hypersonic boundary layer with viscous interaction are investigated analytically and experimentally. For strong and moderate viscous interaction, the heat transfer on a flat plate and a slender wedge is calculated by use of the local similarity technique to solve the boundary layer equations and the tangent wedge approximation to determine the inviscid pressure. The experiments are conducted at Mach numbers of 16 and 20, at unit Reynolds numbers of 2.3 and 130,000/ft, and at the cold wall condition. The analytical and experimental results are in good agreement. For moderate blowing, it is found that the effects of viscous interaction dominate the flow when the interaction is strong and that the effects of blowing become more important as the strength of the viscous interaction decreases.
