Abstract

The aim of this paper is the study of the influence of the inlet pressure on the behaviour of the structure of the flowfield in a DF chemical laser. The unsteady complete Navier-Stokes equations have been solved numerically in the nozzles and in the laser cavity. The results show the different structures of the flow, the effect on the shape of the diffusion zone in the laser cavity and the distribution of the small-signal gain coefficients for a rotational-vibrational transition.
