“…In recent years, the lattice Boltzmann method (LBM) has been developed into an effective and powerful computational fluid dynamics technique. It has been widely used in modelling complex multiphase flows including boiling (Chang, Huang & Lu 2017;Chang et al 2019), droplet evaporation and condensation (Ledesma-Aguilar, Vella & Yeomans 2014; Hessling, Xie & Harting 2017) and the moving contact line problem (Kusumaatmaja, Hemingway & Fielding 2016). The multiphase LBM, as a diffuse-interface model, can automatically capture the GLI by incorporating two-phase interactions.…”

The width effect on contact angle hysteresis in a microchannel with patterned heterogeneous surfaces is systematically investigated. In the model, identical defects periodically appear on the background surface. To this end, a droplet's evaporation and condensation processes inside the microchannel are studied by theoretical analysis and numerical simulation based on a diffuse-interface lattice Boltzmann method. The microchannel width effect on the system's equilibrium properties is studied. The results demonstrate that the number of equilibrium configurations increases linearly with the microchannel width ( $b$ ), and has a quadratic relationship with the cosine of the reference contact angle and the heterogeneity strength ( $\varepsilon$ ). The average most stable contact angle is independent of $b$ and is always equal to the contact angle predicted by the Cassie–Baxter equation. For contact angle hysteresis ( $H$ ), when the microchannels are narrow and wide, there are individual-effect-dominated hysteresis (IDH) and collective-effect-dominated hysteresis (CDH), respectively. The IDH and CDH are hysteresis modes corresponding to the jumping behaviour of contact lines affected by individual defects and two neighbouring defects, respectively. Based on the graphical force balance approach, we establish a scaling law to quantify the connection between $H$ , $b$ and $\varepsilon$ . Specifically, in the IDH mode, $H\sim b \varepsilon ^2$ , while in the CDH mode, $H$ increases linearly with $\varepsilon$ but nonlinearly with $b$ .

“…Here, we analyze and discuss the applicability of the present theory in an extended parameter space through a quantitative comparison to numerical simulations. A number of numerical methods have been successfully applied to bubble dynamics, such as boundary integral method (BIM)/boundary element method (BEM) [61,65], finite difference method (FDM)/finite volume method (FVM)/Eulerian finite element method (EFEM) [66,67], smooth partial hydrodynamics (SPH) [68], and lattice-Boltzmann method (LBM) [69,70]. Here we choose three representative methods, namely BIM, EFEM, and SPH for the comparison.…”

In this work, we established a novel theory for the dynamics of oscillating bubbles such as cavitation bubbles, underwater explosion bubbles, and air-gun bubbles. For the first time, we proposed bubble dynamics equations that can simultaneously take into consideration the effects of boundaries, bubble interaction, ambient flow field, gravity, bubble migration, fluid compressibility, viscosity, and surface tension while maintaining an elegant mathematical form. The present theory unifies different classical bubble equations such as the Rayleigh-Plesset equation, the Gilmore equation, and the Keller-Miksis equation. Furthermore, we validated the unified theory with experimental data of bubbles with a variety in scales, sources, boundaries, and ambient conditions and showed the advantages of our theory over the classical theoretical models, followed by a discussion on the applicability of the present theory based on a comparison to simulation results with different numerical methods. Finally, as a demonstration of the potential of our theory, we modeled the complex multicycle bubble interaction with wide ranges of energy and phase differences and gained new physical insights into inter-bubble energy transfer and coupling of bubble-induced pressure waves.
