    Written by best-selling author, John D. Anderson, Jr., this book covers the subject of sustained hypersonic flight, the technology behind the Space Shuttle and other high speed flight vehicles. Anderson's book offers timely and up-to-date information on hypersonic flow-an area that has grown explosively in the last decade. This proceedings book presents the results of the 31st International Symposium on Shock Waves (ISSW31), held in Nagoya, Japan in It covers among others blast waves, chemical reacting flows, chemical kinetics, detonation and combustion, flow visualization, and shock waves in .

      There are complex corner vortex flows in a rectangular hypersonic inlet/isolator. The corner vortex propagates downstream and interacts with the shocks and expansion waves in the isolator repeatedly. The supersonic corner vortex in a generic hypersonic inlet/isolator model is theoretically and numerically analyzed at a freestream Mach number of The cross-flow Cited by: Full text of "Interferometric data for a shock-wave/boundary-layer interaction" See other formats.

A complex flow structure often includes a lip shock wave associated with the beveled expansion fan and wake trail adjacent to the shear layer confluence. The corner expansion process is an expansion fan pattern changed by the presence of the approaching boundary layer and radius of the bevel or shoulder, RC. The wake flow features show several Author: Rakhab C. Mehta.

The second type of interaction is called a shock wave-boundary layer interaction and will be described in the next section. A viscous interaction is a pressure interaction between the hypersonic boundary layer and outer inviscid flow.

The goal of this study is to assess CFD capability for the prediction of shock wave laminar boundary layer interactions at hypersonic velocities. More specifically, the flow field over a double-cone configuration is simulated using both perfect gas and non-equilibrium Navier–Stokes models.

Non-normal effects and global modes. Abstract Laminar-turbulent transition in a hypersonic boundary layer can be influenced by imperfections on the wall surface.

Transition can be delayed or accelerated depending on the type, configuration and location of the imperfections.

Both natural transition and the transition triggered by the imperfections are poorly understood. This.
