Description of Research
Chemical processes are important in flowfields related to aircraft and spacecraft. Typically, one seeks to predict temperature, heat flux, pressure, and species concentrations in such flowfields in order to assess, for example, thermal loads and combustion efficiency. Recent research has focused on the development of theoretical models to accurately predict thermal and chemical non-equilibrium effects in hypersonic flows. Information theoretic ideas were used to derive an expression for the (quantum) state-specific rate coefficient for the dissociation of diatomic molecules at high temperatures.

Dr. Gonzales' future research will focus on the impact of commercial jet aircraft exhaust on the environment. Here an atmospheric chemistry code will be coupled to a computational fluid dynamics code to study the time evolution of exhaust species in the wake/vortex flowfield.
