一、试验方法 雾化槽式喷嘴实质上就是在逆气流喷射的直流式喷嘴上游加装一个槽形挡板。为简化起见,首先研究单个雾化槽式喷嘴。 试验先后在d=135mm圆形和200mm×100mm矩形试验段中进行。雾化槽与喷油杆均横贯试验段截面(图1)。共试验了24个工况,其参数范围如下:气流速度V_a=56～114m/s;供油压差△P_t=(1.96～14.7)×10~5Pa;喷嘴 First, the test method The atomized trough nozzle is essentially in the anti-airflow jet nozzle upstream to install a channel-shaped baffle. For simplicity, a single atomizer trough nozzle was first studied. The test was carried out in a d = 135 mm circular and 200 mm × 100 mm rectangular test section. Both the atomizing tank and the injection rod cross the section of the test section (Figure 1). A total of 24 working conditions were tested and the parameters were as follows: air velocity V_a = 56 ~ 114m / s; pressure difference ΔP_t = (1.96 ~ 14.7) × 10 ~ 5Pa;
