本文介绍了一些向具有室温和高压的静止空气中进行喷射的多孔柴油雾注之形状及相邻雾注间的空气运动的试验结果。 由这些实验可得出以下结论:(1)被测量的雾注的尖端贯穿度、锥角及当量锥角不受旁边其它雾注的影响。(2)多孔雾注的初始段长度和贯穿段长度大于单孔雾注。(S)在相邻雾注之间、沿喷咀尖端方向存在有空气运动。(4)壁面之间喷射雾注周围的空气速度是无壁面情况时空气速度的两倍。(5)喷咀尖端方向上火焰的增大是随喷孔数目的增加而发展的。
This paper presents some experimental results of the shape of porous diesel mist injected into still air at room temperature and high pressure, and the air movement between adjacent mist. The following conclusions can be drawn from these experiments: (1) The tip penetrations, cone angles, and equivalent cone angles of the measured mist are unaffected by other misty notes alongside. (2) The length of the initial section of the porous mist injection and the length of the penetration section are larger than the single-hole mist injection. (S) There is air movement along the tip of the nozzle between adjacent mist injection. (4) Spray between wall surfaces The velocity of the air around the atomizer is twice the air velocity in the absence of the wall surface. (5) The increase of the flame in the direction of the nozzle tip is developed with the increase of the number of spray holes.
