Abstract

The results of three-dimensional computational fluid dynamics model calculations are reported in detail and compared to available experimental results [Nikolaev et al., IEEE J. Quantum Electron. 38, 421 (2002)]. It is shown that the model is applicable to high pressure, ejector type chemical oxygen-iodine laser (COIL), reasonably reproducing the measured gain, temperature, static pressure and gas velocity. A previous model which included I₂(A′³Π_2u), I₂(A ³Π_1u) and O₂(a ₁Δ _gv) as significant intermediates in the dissociation of I₂ [Waichman et al., J. Appl. Phys. 102, 013108 (2007)] reproduced the measured gain and temperature of a low pressure supersonic COIL. The previous model is complemented here by adding the effects of turbulence, which play an important role in high pressure COILs.
