Hypersonic and Supersonic Flight - Advances in Aerodynamics, Materials, and Vehicle Design

wave with a wedge is discussed. Mathematical modeling of the flow around the wedge

is carried out with Euler equations. These equations describe the unsteady flow of an

inviscid compressible fluid around a wedge in a two-dimensional domain. To take into

account high-temperature effects on super- and hypersonic flows, the model developed

takes into account equilibrium chemical reactions in the air, ionization, and

dissociation processes. The initial parameters of the flow are set equal to the parameters

of the flow behind the shock wave in accordance with the Rankine–Hugoniot

relations. The solutions to the problem obtained with the model of ideal perfect gas

and the model taking into account high-temperature effects in the air are compared.

The influence of high-temperature effects on the distribution of flow quantities is

discussed.
