摘 要: | 进行了用冷态实验模拟爆震室中雾化性能的研究。实验中,采用水/压缩空气模拟煤油/氧气,测试了与爆震试验供应压力一致的各工况下的混合物索太尔平均直径(SMD)。研究结果表明:随着空气压力、水压力的增大,SMD减小;所建立的冷态雾化和混合实验台可以满足模拟热态实验雾化效果的需要,且带头部离心喷嘴的爆震性能好于直射喷嘴的。

Abstract: | The atomization performance of Pulse Detonation Chamber is investigated using cold test.In the tests,kerosene and oxygen are simulated with water and compressed air respectively.Sauter Mean Diameters(SMD) of mixture were measured at various operation conditions accordant with detonation test supply pressure.The results show that SMD decrease with the increase of the pressure of air and water,and cold device can meet the requirement of simulating hot test atomization performance.It is concluded that atomization performance of a centrifugal nozzle is superior to a simple nozzle. |
