Abstract:

In this report, we model the electronic conductivity of low-temperature plasma formed due to thermal ionization of dry air in normal shock waves at hypersonic and hypervelocity Mach numbers 630 km s-1 using the multiterm Boltzmann equation, Monte Carlo collision, and Cheetah 9.0 equation of state methods.
