分析包括使用直径为2厘米、3厘米和5厘米的平板旋转圆盘进行的实验，这些圆盘具有受控的无光工作面。转速为19000~70000转/分，进水量分别为0.121、0.421和0.771 g/S。得到了最大液滴直径与圆盘尺寸、液体流量和转速之间的关系，并用无因次群表示了它们之间的一般关系。分散的程度用数值形式表示为Rosin-Rammler分布常数。(A)S.M.D.之间有很好的相关性。和(B)最大液滴直径，以及无量纲基团的适当乘积。分布常数用速度和流量来表示，但关联性不如(A)和(B)的情况令人满意。没有给出关于断裂模式的信息，但探讨了分析方法的局限性。
The analysis covers experiments made using flat rotating disks of 2, 3 and 5 cm diameter having controlled matt working surfaces. Rotational speeds varied from 19 000-70 000 rev/min and water feed rates were 0.121, 0.421 and 0.771 g/s. The independent variation of Sauter mean diameter (S.m.d.) and of maximum droplet diameter with disk size, liquid flow rate and rotational speed were found and the general correlation is expressed using dimensionless groups. The extent of the dispersion is numerically expressed as a Rosin-Rammler distribution constant. Good correlation was found between both (a) S.m.d. and (b) maximum droplet diameter, and the appropriate products of dimensionless groups. The distribution constant is expressed empirically in terms of speed and flow rate, but the correlation is less satisfactory than in the case of (a) and (b). No information is given on the mode of fracture, but limitations of the analytical method are explored.
