Abstract

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.
