本文通过质量与能量守恒积分分析,提出激波诱导液滴破碎中液滴尺寸与分布的更新预测形式,并验证其可依据速度比和流体性质在合理精度内预测液滴尺寸及分布偏斜。

摘要:

我们利用质量与能量守恒方程的积分分析,来确定激波诱导液滴破碎过程中的液滴尺寸及其分布。所得结果给出了液滴尺寸作为其最终速度函数的更新形式,该形式源自一系列应用于不同雾化几何构型的研究工作。与实验数据的对比证明了该方法的有效性和实用性。激波诱导的液滴尺寸和分布可以作为液滴速度比和流体性质的函数,在合理精度范围内进行预测。该结果还揭示了动能亏损传递为表面张力的动力学过程,以及由于对速度比的非线性依赖而导致的液滴尺寸分布偏斜。

英文摘要:

We use an integral analysis of conservation equations of mass and energy, to determine the drop size and distributions during shock-induced drop break-up. The result is an updated form for the drop size as a function of its final velocity, from a series of work applied to various atomization geometries. Comparisons with experimental data demonstrate the validity and utility of this method. The shock-induced drop size and distributions can be predicted within reasonable accuracy as a function of the drop velocity ratio and fluid properties. The result also illustrates the dynamical process of kinetic energy deficit transferred to the surface tension energy, and the skewing of the drop size distribution due to the non-linear dependence on velocity ratio.
