摘要

以气液两相双腔自激振荡燃油喷嘴为研究对象，采用数值模拟的研究方法，研究在不同结构参数和温度下对于燃油内部流动特性的影响。结果表明：不同结构参数和燃油温度对内部流动特性的影响有明显区别，燃油温度升高，内部流动特性（质量流率、空穴数、流速和湍动能）均会逐渐增大。

Abstract:

In this paper, the gas-liquid two-phase double-cavity self-excited oscillating fuel nozzle is taken as the research object, and numerical simulation method is adopted to study the influence of different structural parameters and temperatures on the internal flow characteristics of fuel.The results show that the effects of different structural parameters and fuel temperature on internal flow characteristics are obviously different, and the internal flow characteristics (mass flow rate, the cavity number, flow rate and turbulent kinetic energy) will increase gradually with the increase of fuel temperature.

Key words: Nozzle Structural parameter Cavitation Flow characteristics Numerical simulation
