Based on the hypersonic flow field data obtained in the repeatable laboratory simulations using ballistic range [11] or plasma wind tunnel [12], more practical physical models of hypersonic flow field can be established using the CFD technique [17].
In this paper, a high-order accurate finite difference method is used to simulate the hypersonic flow field over the blunt wedge with a smooth wall and rough wall, and the effect of roughness on the flow state in the boundary layer is discussed.
[14-16] in analysis of simply supported panels fluttering in hypersonic flow. Two nonlinear aerodynamic terms, [([partial derivative]w/[partial derivative]x).sup.2] and ([partial derivative]w/[partial derivative]x)([partial derivative]w/[partial derivative]t), taken from the third-order piston theory, were added to the linear piston theory to account for the aerodynamic nonlinearity [17].
The Turbulence model k- omega simulates the hypersonic flow conditions, thereby capturing shocks.
Because hypersonic flow is far more complex than low speed flow (low Mach numbers flow and incompressible flow), the prediction of hypersonic boundary layer transition has become more difficult, which makes the transition mechanism of hypersonic boundary layer unclear.
The final chapter addresses hypersonic flow, assessing the accuracy of numerical simulation through NATO RTO hypersonic research findings.

Eighteen chapters are presented in sections on inviscid hypersonic flow, viscous hypersonic flow, and high-temperature gas dynamics.
Often its air compressors were not needed for this purpose, and the Navy took advantage by using those compressors to run this wind tunnel with a continuous hypersonic flow. By contrast, most other high-speed wind tunnels used compressed air from a tank, for run times of less than a minute.
Panaras and Drikakis investigated spiked blunt bodies in supersonic and hypersonic flow and showed that unsteady flow was characterized by periodic radial inflation and conical separation bubble collapse [14].
Among the topics are circular cylinder in transonic viscous perfect gas flow, elliptic cylinder in supersonic perfect gas flow, supersonic viscous gas flow over a sphere, blunt axisymmetric bodies in supersonic and hypersonic flow at zero angle of attack, and verification of the numerical simulation method.
