Application of 3-D, Unsteady Navier-Stokes Simulation to Chemical Oxygen-Iodine Laser Technology Development

Three-dimensional, time-dependent solutions of the reacting flow Navier-Stokes equations are applied simulations of chemical oxygen-iodine laser (COIL) hardware. The presented simulations examine various aspects of COIL physics and performance, including mixing nozzle performance as related to flow unsteadiness and diffuser performance as determined by shock-boundary layer interactions.
