The results are described of numerical calculations performed in order to improve understanding of the flow of the glow discharge laser. The Harwell-FLOW3D code was used to model 2-D incompressible flow past a triangular obstacle (representing a design of laser cathode) in a duct. Substantial numerical difficulties were encountered due to the flow being in the laminar/turbulent transition regime, but these were largely overcome. A series of time-dependent calculations including a model heat equation, demonstrates the effect of varying inlet speed on the region downstream of the obstacle.
