Experimental Study on Spray Characteristic of Gas-liquid Coaxial Injectors

Zhenguo Wang

Abstract

Spray characteristics of gas-liquid coaxial shear and swirl injectors were studied by conducting experiments.The results suggest that the injector outlet expanding can improve atomization performance;for the two kind of injectors,that is,gas-liquid coaxial swirl injectors and gas-liquid coaxial swirl injectors,with a proper indent length,they have good atomization performance and proper flow performance;and under the same conditions,gas-liquid coaxial swirl injectors have better atomization performance than gas-liquid coaxial swirl injectors.
