Paper Abstract

The aim of this paper is first the numerical study of the flowfield structure in a DF chemical laser resulting from a high average pressure in the exit plane of the nozzles and second, the analysis of the influence of the diffusion coefficient multiplier model on the evolution of the small signal gain coefficient accross and along the laser cavity. The numerical code is based on the solving of the complete unsteady two-dimensional Navier-Stokes equations in the nozzles and in the laser cavity with a finite difference explicit predictor-corrector scheme and a time splitting technique.
