Abstract

The aim of this work is to describe the unsteady two-dimensional flow in an excimer laser cavity. In order to do this, a numerical model based on a finite difference scheme associated with a corrected transport algorithm (SHASTA model) has been developped to calculate the flowfield in "L.U.X." laser of Institut de Mecanique des Fluides de Marseille. The evolution of longitudinal and transverse waves along the cavity and the damping of density perturbations in the discharge volume have been drawn. The numerical results are compared to the experimental evolution of density at an upstream discharge volume position.
