WebIn addition, the reproducti on of hypersonic flight conditions at ground experimental facilities is in many cases impossible. As a result the theoretical simulation of hypersonic flow past a spacecraft is of great importance. Use of numerical calculations with their relatively small cost provides with highly informative flow data and gives an WebVirginia Tech WebA flow is called hypersonic if the Mach number is greater than 5. This means that the flow speed is more than five times the speed of sound. In air at room temperature, the speed of sound is around 340 m/s, so a Mach 5 flow would have a flow speed of 1.7 km/s or just over 6,000 km/h.

WebThree mechanisms convert mechanical energy to thermal energy in a hypersonic flow. The first is the viscous dissipation of kinetic energy by shear stresses adjacent to a surface. The second is also viscous dissipation but the result of normal stresses acting on the compressed air. WebWhile the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
