Paper Abstract

A three-dimensional (3D) computational fluid dynamics (CFD) model has been applied on a fast-axial-flow CO2 laser. Using a control volume method, a set of governing equations of the model is dispersed and numerically solved. These equations describe the flowing and heat-conducting processes in the discharge tube of the laser. A model, method of solution and computational and experimental results are described and presented in this paper. The parameters of gas pressure, velocity, temperature, density and turbulence energy are obtained by theoretical modeling. The computational results are in very good agreement with the experimental data within a broad range of parameters.
