“…In hypersonic research area, there is binary scaling for non-equilibrium processes involving two-body molecular collisions [ 4 ]. This binary scaling parameter has been demonstrated for the blunt-body stagnation shock layer where the non-equilibrium process is dominated by the two-body dissociation reactions rather than the three-body recombination reactions [ 10 ]. However, the binary scaling is not applicable for air-breathing hypersonic vehicles such as X-43a and trans-atmospheric vehicles such as X-37b.…”

“…Thirdly, the binary scaling approach, strictly speaking, is built upon the hypothesis of a single species mixture. That approach has therefore limited application for more complex mixtures such as air [7]. Finally, as altitude decreases, density increases and both l D and l R become smaller.…”

“…Chemical kinetics are dominated by two-body dissociation reactions in some regimes while three-body collision processes are relatively unimportant (Hall et al 1962;Hornung 1988), which is the reason why the binary scaling law is well suited for high-altitude airflow with coupled chemical non-equilibrium. Ellington (1967) examined the limitations of binary scaling for hypersonic flight and suggested that there exists a class of low-density hypersonic flows for which the binary scaling law is still applicable. Lee & Baker (1969) identified the controlling parameter for non-equilibrium air dissociation and ionization using a simplified set of boundary-layer equations and demonstrated binary scaling by comparing with axisymmetric solutions.…”
