Abstract:

The performance potential of a continuous wave cw laser operating on the hydrogen fluoride chain reaction are predicted analytically using computer models for mixing dynamics, fluid mechanics, and laser kinetics. The results show very favorable performance however, experimental data from pulsed and cw experiments fall below the predictions by factors of approximately 4 and 30, respectively. Possible reasons for this disagreement include 1 use of incorrect rate coefficients in the model, 2 fluid mechanicalreactive flow interactions in the cavity not included in the model, and 3 inadequate control of the variables in the experiments. These possibilities are discussed in some detail and it is recommended that experimental work in each area should be undertaken concurrently so that the performance potential of the HF chain reaction can be evaluated in a timely manner.
