关 键 词：DF chemical laser HYLTE nozzle mixing method research
摘 要：正The feasibility of High-speed imaging and Nano-based Planar Laser Scattering（NPLS） which are used to evaluate the mixing performance of a designed HYLTE（HYpersonic Low TEmperature） nozzle has been *** order to visualize the expanding part that includes transverse injecting and mixing process,a single throat nozzle laser with windows has been designed and manufactured. Two simulation methods have been studied to get the flowfield of HYLTE nozzle and cavity. In order to visualize therealmixing flowfield in laser,one 3D procedure concerning 15 species and 102 one-way primary reactions expressed by finite rate equations are ***,the LES method has been put forward to research vortex structure and mixing mechanism.
