The Development of High Order Numerical Techniques for Reentry Simulation of Hypersonic Spacecraft [PDF]
, 1991 The primary difficulty encountered when simulating hypersonic flow is that the flow normally includes strong nonlinear discontinuities. These discontinuities fall into three broad classes: shocks, slip-lines, and rarefaction waves.
