Paper Abstract

Theoretical models for the chemical lasers depend on a variety of assumptions and empirical data to provide closure and simplify solution of the governing equations. Among the various assumptions and empirical data built into models for chemical lasers are assumptions regarding steadiness in the time domain and geometric similarity of the computational domain. The work discussed here is directed toward elucidating and increasing the understanding of the assumptions underlying chemical laser models and the implications for the modeled physical processes underlying the chemical laser, driven by current directions in the development of this technology. This is directly linked to efforts to achieve improved chemical laser efficiencies and performance, as excursions outside the assumed to be ‘well understood’ traditional operational parameter space are increasingly necessary.
