Adaptation of a wall-catalytic fluorine recombination model to fluid-dynamic computations in an HF laser nozzle

This paper discusses the adaptation of a detailed fluorine wall-recombination model into the fluid-dynamic equations governing the flow of dilute atomic fluorine in a tiny generic-type nozzle reminiscent of those found in HF lasers. The wall-recombination model is briefly described as are the fluid-dynamic equations making up the computational framework in which this study was made. Results are given for a range of nozzle wall temperatures from 450 K to 650 K. These results are compared to those obtained assuming a fully-catalytic wall. 16 references
