“…Cavitation, as one of the hot topics in the multiphase flow field, is usually accompanied by a variety of complex macroscopic dynamic. In terms of research on cavitation bubble thermodynamics, Yang et al first established a thermodynamic model of cavitation bubble collapsing by using the improved thermal DDF-LBM [ 43 , 44 ]. Moreover, a multicomponent DDF LBM was developed on this basis, and the validity of the model was verified by theoretical and experimental comparison, which can be used for the thermodynamic study of multicomponent multiphase flow [ 45 ].…”

“…The interparticle interactions are the underlying engine behind the complex THNE features of multiphase flows. The aforementioned models and their revised versions have been applied successfully to the study of fundamental phenomena and mechanisms of multiphase flows in science and engineering, ranging from droplet evaporation (Ledesma-Aguilar, Vella & Yeomans 2014; Safari, Rahimian & Krafczyk 2014;Zarghami & Van den Akker 2017;Qin et al 2019;Fei et al 2022) to droplet deformation, breakup, splashing and coalescence (Wagner, Wilson & Cates 2003;Wang et al 2015a;Wang, Shu & Yang 2015b;Chen & Deng 2017;Wen et al 2017Wen et al , 2020Liu et al 2018;Liang et al 2019;Yang et al 2022b), collapsing cavitation (Chen, Zhong & Yuan 2011;Falcucci et al 2013;Kähler et al 2015;Sofonea et al 2018;Yang et al 2020Yang et al , 2022a, acoustics levitation (Zang 2020), nucleate boiling Fei et al 2020), ferrofluid and electro-hydrodynamic flows (Falcucci et al 2009;Hu, Li & Niu 2018;Liu, Chai & Shi 2019), hydrodynamic instability (Zhang et al 2001;Fakhari & Lee 2013;Liang et al 2014Liang et al , 2016aLiang, Shi & Chai 2016b;Yang, Zhong & Zhuo 2019;Tavares et al 2021), dendritic growth (Rasin et al 2005;Rojas, Takaki & Ohno 2015;Sun et al 2016a,b), heat and mass transfer in porous media (Chen et al 2015;Chai et al 2016…”

The aim of this paper is twofold: the first aim is to formulate and validate a multi-scale discrete Boltzmann method (DBM) based on density functional kinetic theory for thermal multiphase flow systems, ranging from continuum to transition flow regime; the second aim is to present some new insights into the thermo-hydrodynamic non-equilibrium (THNE) effects in the phase separation process. Methodologically, for bulk flow, DBM includes three main pillars: (i) the determination of the fewest kinetic moment relations, which are required by the description of significant THNE effects beyond the realm of continuum fluid mechanics; (ii) the construction of an appropriate discrete equilibrium distribution function recovering all the desired kinetic moments; (iii) the detection, description, presentation and analysis of THNE based on the moments of the non-equilibrium distribution ( $f-f^{(eq)}$ ). The incorporation of appropriate additional higher-order thermodynamic kinetic moments considerably extends the DBM's capability of handling larger values of the liquid–vapour density ratio, curbing spurious currents, and ensuring mass/momentum/energy conservation. Compared with the DBM with only first-order THNE (Gan et al., Soft Matt., vol. 11 (26), 2015, pp. 5336–5345), the model retrieves kinetic moments beyond the third-order super-Burnett level, and is accurate for weak, moderate and strong THNE cases even when the local Knudsen number exceeds $1/3$ . Physically, the ending point of the linear relation between THNE and the concerned physical parameter provides a distinct criterion to identify whether the system is near or far from equilibrium. Besides, the surface tension suppresses the local THNE around the interface, but expands the THNE range and strengthens the THNE intensity away from the interface through interface smoothing and widening.

“…Numerous studies have been carried out to simulate the growth or collapse processes of cavitation bubbles with pseudo-potential LBM [25,40,41,39,37,38,51,52,1,20,21,50,19,22], but most of these studies have simulated only the growth or collapse processes. In all the LBM-based cavitation bubble inception or growth studies, a vapor nucleus is initialized, and the bubble is formed by nucleus growth under the pressure difference between the bubble and the surrounding liquid [39,37,48,12].…”

A two-dimensional double-distribution-function thermal pseudopotential lattice Boltzmann model is applied to study the inception and evolution processes of cavitation bubbles. The inception process is realized by a high-temperature spot, while the growth and collapse processes are realized through the variation of the boundary pressure. Interactions between two equal-sized bubbles and two unequal-sized bubbles are systematically investigated. A modified Rayleigh-Plesset equation for the two cavitation bubbles that includes a weak interaction and thermal effects is proposed. For the weak interaction mode, the highest collapse temperature is lower than the initial input temperature due to energy dissipation. However, for the strong interaction mode, the maximum temperature is ultimately higher than the initial input temperature due to the superposition of an exothermic process. For the weak interaction mode between two unequal-sized bubbles, when the distance between the two bubbles is small, the re-entrant jets and pressure wave generated by the small bubble cause the inner wall of the large bubble to flatten. For the strong interaction film-thinning mode, the microjets and high pressure generated by the small bubble change the collapse direction of the large bubble.
