| 摘 要： | 一、稳定器水平安放时油雾射流的穿透深度与最大浓度线 二元试验段、连续取样的燃气分析系统及实验方法的详细说明见文献2、3]。 稳定器与油雾射流的相对位置如图1所示。在试验段中安装了火焰稳定器之后,使流场发生了改变,火焰稳定器既改变了气流的方向,又改变了气流速度的大小,而且在稳定器截面不同点处气流速度的方向与大小又各不相同,因此对油雾射流的穿透深度和最大浓度线必然产生影响。

| Abstract: | The penetration and the maximum concentration line of fuel spray are very important for designing afterburner. The effects of airstream velocity, pressure drop across the orifice of fuel ejector and diameter of fuel ejector on the penetrationand the maximum concentration lion of fuel spray have been studied. When the flameholder is mounted in the test section, both the direction of flow and the magnitude of velocity vary consequently. It is necessary to consider the contribution of these factors to the fuel distribution. Therefore the effects of vertex angle and position of the flameholder on the penetration and maximum concentration line of fuel spray are further investigated experimentally. The expirical formulas are obtained from the test results. |
