Hypersonic Flows

  • Mrinal KaushikEmail author


It is generally well accepted that all those flows, having the Mach numbers more than 5, are termed as hypersonic flow. However, it is natural to ask, why this limit is set to Mach 5 only? why not at Mach 4 or even at Mach 6? One may also ask, how and in what respect the shock wave produced at hypersonic Mach number is distinct than the shock produced in a supersonic flow? To answer these questions, we must have a thorough understanding of the characteristics associated with a hypersonic flow regime. In this chapter, we have attempted to describe these attributes which, in turn, represent a “formal definition” of the hypersonic flow.
