Abstract:

Time-dependent finite-difference solutions of the two-dimensional Navier-Stokes equations, fully coupled with the appropriate finite-rate chemical kinetic equations, are obtained for HF chemical laser flows. These solutions demonstrate the practicality of Navier-Stokes solutions for chemical laser flows. Results are given for steady flows where large pressure gradients are calculated as a natural part of the Navier-Stokes solutions. In addition, the effect of unsteady fluctuations intentionally introduced at the cavity inlet are studied. Such unsteady mixing increases the laser gain by more than a factor of two. Author
