Two micron-sized water droplets approaching each other do not always coalesce due to the cushioning effect of the air between them. When the droplets do not carry any electrical charges, one needs to consider the breakdown of hydrodynamics at very small scales to decide whether the droplets collide and coalesce or not. In contrast, two approaching droplets that are oppositely charged always coalesce if the charges are large enough. To find the charge for which the transition to charge-dominated collisions occurs, we computed the collision efficiency of charged, hydrodynamically interacting droplets settling in quiescent air, including the noncontinuum regime at small interfacial distances. For oppositely charged droplets, we find that the transition occurs when a saddle point of the relative droplet dynamics exits the region within which the continuum hydrodynamics breaks down. For cloud droplets with radii 16 and , we observe that the transition occurs at elementary charges . For charges smaller than this, we predict that the coalescence rate depends primarily upon the Knudsen number (, the ratio of the mean-free-path of air to the mean droplet radius), whereas coalescence for much larger charges does not depend upon . For droplets charged with the same polarity, we find the critical charge to be substantially larger ( for the above radii) for reasons that we discuss.

Most of the studies on pressure fluctuations in wall-bounded turbulent flows aim at obtaining statistics as power spectra and scaling laws, especially at the walls. In the present study we study energetic coherent pressure structures of turbulent channel flows, aiming at a characterization of dominant coherent structures throughout the channel. Coherent structures are detected using spectral proper orthogonal decomposition (SPOD) and modeled using resolvent analysis, similarly to related works dealing with velocity fluctuations but this time using pressure fluctuations as the output of interest. The resolvent operator was considered with and without the Cess eddy-viscosity model. Direct numerical simulations (DNSs) of incompressible turbulent channel flows at friction Reynolds numbers of approximately 180 and 550 were employed as databases in this study. Three representative dominant structures emerged from a preliminary spectral analysis: near-wall, large-scale, and spanwise-coherent structures. For frequency–wave number combinations corresponding to these three representative structures, SPOD results show a strong dominance of the leading mode, highlighting low-rank behavior of pressure fluctuations. The leading resolvent mode closely agrees with the first SPOD mode, providing support to studies that showed better performance of resolvent-based estimators when predicting pressure fluctuations compared to velocity fluctuations [Amaral et al., J. Fluid Mech.927, A17 (2021)]. The dominant mechanisms of the analyzed modes are seen to be the generation of quasistreamwise vortices with pressure fluctuations appearing close to vortex centers. A study on the individual contributions of the nonlinear terms (treated as forcing in resolvent analysis) to the pressure output reveals that each forcing component plays a constructive role to the input-output formulation, which also helps understanding the weaker role of forcing “color” in driving pressure fluctuations.

The viscoelastic relaxation time of a polymer solution is often measured using capillary breakup extensional rheometry (CaBER) where a droplet is placed between two plates which are pulled apart to form a thinning filament. For a slow plate retraction protocol, required to avoid inertio-capillary oscillations for low-viscosity liquids, we show experimentally that the CaBER relaxation time inferred from the exponential thinning regime is in fact an apparent relaxation time that may increase significantly when increasing the plate diameter and the droplet volume. Similarly, we observe that increases with the plate diameter for the classical step-strain plate separation protocol of a commercial (Haake) CaBER device and increases with the nozzle diameter for a dripping-onto-substrate (DoS) method. This dependence on the flow history before the formation of the viscoelastic filament contradicts polymer models such as Oldroyd-B that predict a filament thinning rate ( being the model's relaxation time), which is a material property independent of geometrical factors. We show that this is not due to artifacts such as solvent evaporation or polymer degradation and that it can be rationalized by finite extensibility effects (FENE-P model) only for a dilute polymer solution in a viscous solvent, but not for semidilute solutions in a low-viscosity solvent.

The computation of the second-order mean wave drift loads on a body with thin perforated shells is fundamental and relevant to a wide range of applications in marine engineering, marine aquaculture, offshore renewable energy, etc. In this work, formulations involving a control surface at a distance from the body are proposed to compute drift loads on structures composed of an impermeable hull and a perforated surface accurately and efficiently. Applications of mathematical identities and conservation of fluid momentum are proved to yield identical formulations. Due to the presence of perforated shells, an integral caused by the dissipation through perforated surfaces is included in the formulation. The present formulation cannot only give all six components of the mean wave drift force and moment, but also determine the drift loads on each individual body of a multibody system. The developed formulations are applied to a series of structures, including single-body and multibody systems. It is found that the perforated surface integral plays a secondary role in the computation of drift loads. Besides, perforating body surfaces can mitigate the near-trapped wave motion in a multibody system. Compared to a fixed system, the mean wave drift loads can be amplified around the resonance frequencies of body motions. The dissipation through the perforated shell can enhance the damping effect and suppress the excessive motion response, resulting in a reduction in the amplified drift loads.

Capillary imbibition underpins many processes of fundamental and applied relevance in fluid mechanics. A limitation to the flow is the coupling to the confining solid, which induces friction forces. Here we study the effect of coating the solid with a liquid lubricant layer. Using a theoretical framework, we show that for sufficiently small lubricant viscosity, dissipation entirely occurs in the lubricant layer, resulting in a linear growth of the advancing front. We extend our study to forced imbibition, where the same mechanism gives rise to an exponential front growth. This new ability to control multiphase flows in confinement opens new opportunities for flow control in micro and nanofluidic devices.

We report experimental results on the dynamics of large bubbles in a Hele-Shaw cell subject to various inclination angles with respect to gravity. Low Reynolds number cases are studied by injecting bubbles in a stagnant water/UCON mixture in three different Hele-Shaw cell geometry. The leading order rise speed follows the Taylor-Saffman limit which is inversely proportional to the viscosity , but directly proportional to the square of the cell gap and the effective gravity, accounting for cell tilt angle . However, when the cell is increasingly inclined, the bubble buoyancy in the cell gap leads to a substantial decrease in the rise speed, as compared to the Taylor-Saffman speed. Buoyancy pushes the bubble toward the top channel wall, whereby a difference between the lubrication film thickness on top of and underneath the rising bubble occurs. We attribute these observations to the loss of symmetry in the channel gap, due to cell inclination. Nonetheless, the top lubrication film is observed to follow the Bretherton scaling, namely, , where is the liquid surface tension while the bottom film does not exhibit such a scaling. Finally, we illustrate that a model incorporating a friction term to the power balance between buoyancy and viscous dissipation matches well with all experimental data.
我们报告了在与重力呈不同倾角的赫勒-肖池中大气泡的动力学实验结果。通过在三种不同几何形状的 Hele-Shaw 小室中将气泡注入停滞的水/UCON 混合物，研究了低雷诺数情况。前阶上升速度 vb 遵循泰勒-萨夫曼极限，与粘度 η 成反比，但与电池间隙 h 的平方和有效重力成正比，并考虑了电池倾斜角 θ。然而，当电池越来越倾斜时，与泰勒-萨夫曼速度相比，电池间隙中的气泡浮力导致上升速度大幅下降。浮力将气泡推向通道顶壁，因此上升气泡顶部和底部的润滑膜厚度出现差异。我们将这些观察结果归因于细胞倾斜导致通道间隙失去对称性。尽管如此，我们观察到顶部润滑膜遵循布雷特顿缩放比例，即 (ηvb/σ)2/3，其中 σ 是液体表面张力，而底部润滑膜则没有这种缩放比例。最后，我们说明，在浮力和粘性耗散之间的功率平衡中加入摩擦项的模型与所有实验数据非常吻合。
