When a fluid element moves at a hypersonic speed, the kinetic energy is much more than its thermal energy. As a matter of fact, at higher Mach numbers, the ratio of kinetic

In hypersonic flows, the air around the object undergoes rapid compression, leading to the formation of strong shock waves. These shock waves significantly increase the

However, most hypersonic flows encounter strong shock-wave compressions resulting in a high enthalpy gas environment that always associates with nonequilibrium thermodynamic and

So far we have seen the effect of the equilibrium chemistry on the air composition at high temperature in hypersonic flow. The equilibrium chemistry assumes that throughout the

Some Special Aspects of Hypersonic Flow Fields

Boundary-layer transition in hypersonic flows over a straight cone can be predicted using measured freestream spectra, receptivity, and threshold values for the wall pressure

The hypersonic flow field around a blunt cone was simulated using a high-order finite difference method. Fast acoustic waves, slow acoustic waves, entropy waves, and

To analyze the effect of pulse entropy disturbance on a hypersonic flow field over a blunt cone, the steady flow field was obtained using the high-order finite difference method.

An important consequence of the prevailing high temperatures is the high rates of heat- ing of the fuselage. The generation of such large heating rates is due to compressibility

In general, hypersonic flow has four „high“ characteristics: high-temperature, high-pressure, high-speed, and high-frequency, which brings great challenges to researchers. This special topic

Hypersonic vehicles experience extreme temperatures, high heat fluxes, and aggressive oxidizing environments. Here, the authors highlight key materials design principles

Hypersonic flows always exist in a high-enthalpy environment by strong shock wave compression. Under this condition, the flow medium undergoes significant change, which is no longer accurately describable by the
