| 摘 要： | 试验研究了多种结构多斜孔板的流量系数，分析了孔倾角、孔偏角、板厚等几何结构参数，和孔内流动雷诺数、主次流温比、主流马赫数等气动参数对具有复合角的多斜孔板流量系数的影响。研究结果表明：①孔内流动雷诺数小于4000时，流量系数与雷诺数呈线性关系，大于5000时流量系数变化不大；②孔偏角小于40。时，流量系数随孔偏角的增大而...

| Abstract: | Measurements of discharge coefficients for different configurations of the inclined multi-hole plates with compound angle are presented.The factors affecting the discharge coefficient are discussed such as inclination angle,orientation angle,plate thickness,the Reynolds number,temperature ratio between the main flow and the secondary flow and Mach numbers of the main flow.Results show that linear relationship can be observed when Reynolds number is below 4 000,but more than 5 000 it doesn't affect discharge... |
