摘要

在数值模拟的基础上分析了两种不同形状的喷嘴:细长孔喷嘴(或称狭缝喷嘴)和环形喷嘴对于射流碰撞和激波形成以及聚焦的影响.在此基础上又以环形喷嘴为例

分析了喷嘴尺寸对于射流碰撞和激波形成聚焦的影响

得出环形喷嘴相对于细长孔喷嘴具有更好的聚焦效果

以及有效利用激波起爆爆震波的喷嘴与谐振腔的几何匹配关系.

Abstract

This paper analyzed the influence of nozzle shape(slot and annular nozzles) and nozzle size(four different annular nozzles) on jet collision

shock forming and focus based on numerical simulation.It's learnt that annular nozzle's focus effect is better than slot nozzle

and the geometry matching relationship of resonator and nozzle could help ignite the detonation wave by using shock.
