The research investigated experimentally and theoretically the mixing process and its influence on performance of a continuous H2-F2 laser. In the experimental investigation, detailed flow field and chemical species measurements were made in the reaction zone of two parallel flow injector configurations. A hydrogen spray bar injector configuration, similar to many of todays operating chemical lasers, was also tested, but to a lesser extent. For the parallel configuration, one important experimental result was the identification of laminar, transitional, and turbulent regions for the mixing reaction zone. In the theoretical investigation, a simplified theory of a mixing limited production of vibrationally excited HF was constructed. A closed form expression was developed which shows the effects of pertinent flow parameters on laser performance and on HF concentrations for nonlasting cases. Author
