Method research for flow and mixing process of HYLTE nozzle of DF chemical laser

摘要：

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 Tem- perature) nozzle has been studied. In order to visualize the expanding part that includes transverse injecting and mixing process, a single throat nozzle laser with windows has been designed and manu- factured. Two simulation methods have been studied to get the owfield of HYLTE nozzle and cavity. In order to visualize the “real mixing owfield in laser, one 3D procedure concerning 15 species and 102 one-way primary reactions expressed by finite rate equations are built. Also, the LES method has been put forward to research vortex structure and mixing mechanism.
