“…The stretching of the liquid bridge occurs due to the balance between surface tension and the force applied to the retracting substrate. This has been extensively studied in the field of fluid mechanics by Kumar [4], Brulin et al [5,6], and Brulin [7]. Liquid bridge stretching has been investigated both experimentally and theoretically, with several models proposed to describe the behavior, e.g., by Zhang et al [1] and Brulin [7].…”

The dynamics of an axisymmetric liquid bridge stretch are investigated by means of numerical simulations, and the results are validated experimentally. The constant acceleration of the lower substrate stretches the liquid bridge. A simplified simulation model of the experimental setup is developed for the unstructured volume‐of‐fluid two‐phase flow simulation method, which models the lower substrate as a fluid with a prescribed constant acceleration of the retracting substrate. The effect of stretching acceleration, fluid properties, and liquid volume on the liquid bridge dynamics is investigated. It is shown that at low acceleration the length of the lower portion of the bridge is greater than the upper portion, which is reversed at high acceleration. With increasing viscosity, this effect is decreased and the bridge becomes more symmetric.

“…2020) have been extensively studied, and three distinct regimes can be identified by the flow rate provided by the nozzle: a periodic dripping regime for low flow rates, a dripping faucet regime for intermediate flow rates and a jetting regime for high flow rates. (ii) Ligaments stretched between two disks, mainly one of the disks being pulled up at a constant velocity or acceleration, have been studied by Zhang, Padgett & Basaran (1996), Vincent, Duchemin & Villermaux (2014 b ), Zhuang & Ju (2015), Wylie, Bradshaw-Hajek & Stokes (2016) and Brulin, Tropea & Roisman (2020). Two different regimes depending on the Ohnesorge number can be observed: the breakup length stays nearly constant or even decreases with the stretching velocity for low Ohnesorge numbers, whereas it keeps increasing for high Ohnesorge numbers.…”

“…The increase in viscosity has a negative effect on the flow of the particles in the highpressure tank [5]. But on the other hand, this strong combination effect is beneficial to the other processes [6]. The gassolid flow in a pseudo 2D fluidized bed of wet particles with the presence of immersed tubes was studied.…”

The particle feeding system is a prerequisite for the realization of particle impact drilling technology. Because of the high density, the storage and flow of the steel particle are different from those of the other nonviscous particles. The differential equation of the particle movement was built with the liquid bridge force model and the discrete element method. The dynamic movement process and the distribution state of particles in the high-pressure tank were analyzed. For 1 mm steel particles, the mass flow rate decreased with the increase in water content. For 2 mm and 3 mm steel particles, the water content of 15% and 20% was the dividing point of the mass flow rate from increasing to decreasing. When the water content was 10% and 20%, the mass flow rate increased with the steel particle size. But when the water content was 30% and 40%, the mass flow rate decreased with the steel particle size. The study of the control mechanism of the uniformity and stability of particles showed that the funnel flow was the major reason causing the instability and blocking of the feeding process. This research results can provide a basis for the further improvement of the differential pressure feeding system.
