Combustion Phenomena in Chemical Lasers.
Abstract
This final report briefly recapituates the problems studied, the results obtained, and the documents published under the subject project. Attention was focused on the modeling of 'pumping' phenomena (i.e., the formation of activated product gas HF*) in diffusion-type continuous (CW) chemical lasers of hydrogen-fluorine technology. The geometry examined was the 'basic building block' of conventional CW lasers, essentially the plane parallel mixing layer formed by coflowing streams of diatomic hydrogen and monatomic fluorine. (Aside from one task involving the two-step symmetrical chain reaction, in which the hot slow chemical reaction and the cold fast chemical reaction were considered, only the case of high dissociated fluorine was examined). The nature of reported unsteadiness in the lasing portion of the cavity was reviewed, in order to discern whether introduction of time-averaged modeling of turbulent diffusion flames is warranted for quantitatively accurate description of pumping.
