There are strong interactions or couplings among multi-fields in the mixing nozzle of the chemical oxygen-iodine laser(COIL), such as gas-dynamics, chemical reaction kinetics and optics. In this paper, three-dimensional computational flow dynamic technology was applied on the research assessment device improvement chemical laser model by solving the laminar Navier-Stokes equations and transportation equations to study iodine molecule dissociation rate, iodine atom pumping rate, singlet oxygen yield rate and small signal gain distributions. The simulation was done in the condition of that the secondary flow jet would take place in the supersonic section of the nozzle. The detailed flow field and distribution of yield, dissociation and pumping rates were investigated. The distribution charac
