Abstract
We demonstrate the utility of Information Theory for the efficient computation of state-specific reaction rates needed in hypersonic flow computations. We summarize our recent work on vibrational state-specific inelastic rates and dissociation cross-sections. The reaction rate matrix we generate is used to compute the spatially homogenous relaxation process of a diatomic gas dilute in an inert bath gas when the temperature is suddenly raised to a high value. Linear algebraic methods are used to solve the master equation efficiently. We find that almost the entire relaxation process, including vibrational state populations, can be described accurately using data related to the translational temperature only.
