Abstract

• The NO formation in a hypersonic boundary layer is investigated by solving a numerical code that couples fluid dynamics and state-to-state vibrational kinetics. An N2/N/O2/O/NO mixture is considered to simulate the space vehicle Earth re-entry problem. Two new sets of state-to-state rate coefficients of the processes O + N2(v) <-> NO(w) + N and N + O2(v) <-> NO(w) + O are used, calculated in our research group by means of a molecular dynamics approach. Particular attention is payed to rescale the rates of different kinetic processes in order to have a unique vibrational scale for each molecular species (N2, O2, NO). This is not obvious because vibrational levels, obtained from asymptotics of three-body potential of different collisional systems, often do not match, particularly for high-lying vibrational states. The reactions involving NO affect the mass fractions, the molecular vibrational distributions and the heat flux in the boundary layer. (literal)
