摘要: Large Eddy Simulation (LES) has been carried out to analyze species mixing processes in supersonic chemical oxygen-iodine lasers (SCOIL). Detailed data to be gathered from LES permits the analysis of mixing using characteristics of resolved-scale motions and time-dependence. Numerical analysis shows the angle of iodine jet has a significant influence on the mixing process in SCOIL nozzles. An optimization procedure has been constructed to approach the optimal jet angle for the mixing enhancement. Practical implementation of proposed nozzle on experimental setup allowed achieving chemical efficiency of 31.7% under output power 2.7 KW.
