A twodimensional numerical analysis of a ring model of a CW DFCO2 chemical laser with allowance for reagent mixing effects
Abstract
The energy characteristics of a ring model of a CW DFCO2 chemical laser are calculated using twodimensional NavierStokes equations in the narrow channel approximation and a semiempirical turbulence theory. The results obtained are compared with the results of onedimensional calculations. It is found that the principal conclusions of earlier studies generally remain valid; however, the inclusion of transverse inhomogeneities due to a finite mixing rate of oxidizer and fuel flows somewhat decreases the gain in energy with the transition from a plane to a cylindrical geometry of the nozzle unit.
