Abstract

The results of energy analysis of the fragmentation regimes (puffing and microexplosion) of two-liquid droplets of the core-shell type are given. It is shown that using the classical energy approach to describe the hydrodynamic processes, it is possible to predict the critical (necessary and sufficient) conditions for the implementation of fragmentation regimes and their consequences. As distinct from the force approach, it is possible to estimate the discrete energies spent on evaporation, heating, fragmentation, viscous dissipation, and resistance during the motion of the fragmentation front.

双液滴膨化与微爆炸的能量平衡
给出了核-壳型双液滴膨化和微爆炸破碎状态的能量分析结果。结果表明,用经典能量方法来描述水动力过程,可以预测破碎状态及其后果的临界(必要和充分)条件。与力法不同的是,在破碎锋运动过程中,可以估计蒸发、加热、破碎、粘性耗散和阻力所消耗的离散能量。

期刊介绍: Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
