How does the rarefaction of the air affect hypersonic vehicles

The scope, physical concept, and mathematical model for describing how the rarefaction of the air affects on hypersonic flows have been discussed. A new method, namely the data improved Naive-Stroke (DiNS) model, was proposed for the computation of hypersonic shear flows around vehicles flying at altitude of 30-100 km. Validation of the new continuum method has also been done. See pp. 2-17.
