Modeling of Nitrogen Monoxide Formation and Radiation in Nonequilibrium Hypersonic Flows

Prediction of Flight Measurements of High-Enthalpy Nonequilibrium Flow from a CubeSat-Class Atmospheric Probe

“…3.2, but have a somewhat different temperature dependencies as seen in Fig 4.2. At higher temperatures the forward reaction rate coefficient, k f , is higher for the rates of Baulch [12] than the rates of Park [10]. Even though the temperature remains nearly the same as seen in Fig.…”

“…Previous work of Morgan et al [9] uses a set of five reactions to model the reentry environment, which has been used in earlier modeling work [10]. The set of five reactions used in Ref.…”

“…3.2 from Refs. [7] and [10]. The initial freestream mole fractions at each altitude are shown in Tab.…”

“…The rates used come from the set of Park [10] and Baulch [12], and were used in the earlier works [8,10]. The reaction rates have the same activation energies as can be seen in Tab.…”

“…4.3(b) shows the change in NO mole fraction due to variation of the chemical reaction rate. When the rate given by Park [10] is used, more NO is produced in the shock region than when using the rates of Baulch [12]. The mole fraction of NO increases in the region close to the body (near the origin) when using the rates of Park [10] because the rate is higher for the gas temperature close to the body where most collisions occur.…”
