Chemical Laser Analysis Development. Volume V. Reaction Models and Analysis.

Abstract

Chemical kinetics inputs and the results of analyses undertaken are presented in support of the development and application of numerical models for the evaluation of supersonic flow chemical laser performance. Reactions and rate coefficients in use to develop reaction models for H2-F2, H2-F2-CO2, H2-F2-NO-HI, D2-F2 and D2-F2-CO2 chemical lasers are listed and discussed. Detailed results of parametric studies of an H2-F2 direct combustion chemical laser device and of a D2-F2-CO2 transfer chemical laser device are discussed, stressing the potentially important role of the 'hot' reaction (H (or D) + F2 yields HF(v) + F) and of realistic modeling of optical losses, nozzle velocity profiles and, especially, laminar/turbulent fuel/oxidizer mixing rates. An analysis incorporating the production, dissipation and diffusion of turbulent kinetic energy is presented which is shown to realistically model laminar/turbulent mixing in chemical laser cavity flows. Finally, an exploration attempt to use the Error Minimization technique for chemical laser numerical analysis is described. (Author)
