A two-dimensional numerical model of laser-sustained plasmas in flowing argon has been developed. Real gas properties and a complete radiation loss mechanism have been included, but radial velocities in the flowfield are neglected. Calculated plasma size, peak temperatures, and global absorption characteristics are in good agreement with experiment. Radiation loss is found to be the dominant process at high laser powers, though thermal conversion efficiencies in excess of 30% (at 5 kW) can be realized by operating at high flow velocities.
