    The flows which we consider here are appropriate to different stages of hypersonic flow past a semi-infinite fiat plate. In the first instance we shall consider the instability of a non-interactive flow which is appropriate to large distances downstream of the leading edge of the plate. Viscous instability of a strong-interactive hypersonic flow past a flat plate is investi-gated under the assumption that the temperature of the plate is much less than the stagnation temperature. Application of the method of matched asymptotic expan-sions leads to a triple-deck-type formulation for the perturbations. Attention is.

    The subject of laminar-turbulent transition is of considerable practical importance and has a wide range of engineering applications. For this reason, the International Union of Applied Mechanics decided to sponsor a third Symposium on "Laminar-Turbulent Transition", which would be organised by the On the Instability of Hypersonic Flow Past. Experimental Study of the Supersonic Boundary Layer Stability on the Cone-Cylinder Model.- Stability Theory fo Chemically Reacting Flows.- Effects of Suction. Pressure Gradient and Cooling on High Speed Boundary Layer Stability.- On the Instability of Hypersonic Flow Past a Wedge.- On the Subharmonic Instability of Compressible Boundary Layers

    Wedge and Conical Flow Methods: Another relatively simple hypersonic flow analysis technique is an approximate method based on equating the body of interest with a two-dimensional wedge. The flowfield is determined by constructing a wedge tangent to a given point on the body of interest and assuming that the properties at that point on the.   I am intersted in writing a code for "flow over a wedge at hypersonic conditions" problem to get some coding experience. I want to solve Euler (inviscid-compressible)eq's for the problem. Other than Continuity, momentum and energy eq's whether turbulent eq's have to be taken into account?

As a result, our analysis is based on asymptotic scalings which lead to the Rayleigh equation rather than the triple-deck equations. We note that the third type of. The instability of hypersonic boundary-layer flow over a flat plate is considered.

The viscosity of the fluid is taken to be governed by Sutherland's formula, which gives a more accurate representation of the temperature dependence of fluid viscosity at hypersonic speeds than Chapman's approximate linear law.

The stability of hypersonic viscous gas flow in a shock layer in the neighborhood of a flat plate is considered. The stability of the velocity, temperature, density, and pressure profiles calculated on the basis of the complete viscous shock layer equations is investigated within the framework of the linear stability theory with allowance for the shock wave relations.
