Free-surface phenomena play an important role in many engineering applications, such as filling process in casting, etching process and so on. As we know, level set kind method is more accurate than Volume of Fluid kind method. In this paper, we implement a hybrid lattice Boltzmann and particle level set method to simulate filling processes in a 2D cavity. Results obtained by the hybrid lattice Boltzmann and particle level set method show the same filling pattern with other methods in two different Reynolds numbers.

Fluid-structure interaction (FSI) is a very common physical phenomenon which extensively exists in nature, human daily life and many engineering applications. The lattice Boltzmann method (LBM) is an alternative of solving Navier–Stokes equations to obtain complex fluid dynamics. Since the proposal of lattice Bhatnagar–Gross–Krookmodel, the LBM has been improved and applied to various complex flows ranging from laminar flow to turbulent flow and Newtonian flow to non-Newtonian flow. To handle the associated FSI, the bounce-back scheme was proposed and then the immersed boundary method (IBM) was incorporated into the LBM for the simplicity and robustness of IBM in handling complex and moving geometries and the significant efficiency of LBM in solving fluid dynamics. In recent years, the combined frameworks of LBM, that is, bounce-back–lattice Boltzmann method and immersed boundary–lattice Boltzmann method have witnessed a significant development and the successful applications can be found in a range of physical problems such as flow around bluff bodies, flapping wings, wind turbines, aeroacoustics, sea wave modelling and et al. In this paper, the recent progress of LBM and some typical applications involving FSI are reviewed.

“…In addition to the multiphase methods discussed above, LBM has also been coupled with conventional interface tracking techniques such as the VOF and LS methods. Yu et al[121] and Thommes et al[122] for example have looked at coupling the LBM with a LS interface tracking algorithm. These authors used the verification of Young-Laplace's law before applying their methods to problems such as a dam breaking and viscous fingering respectively.…”

Development of a multiphase lattice Boltzmann model for high-density and viscosity ratio flows in unconventional gas wells

The confined flow of multiphase fluids is relevant in a range of applications in both science and engineering. For example, the two-phase flow of gas and liquid can commonly be observed in boilers used for power production, nuclear reactors (particularly in a loss-of-coolant accident) as well as in the transportation of hydrocarbons in the oil and gas industry. The optimal design and operation of these systems relies on an understanding of how the phases interact and the behaviour emergent from these interactions. This thesis studies multiphase flows in the field of natural gas extraction from unconventional reservoirs, with a focus on coal seam gas (CSG). In this context, the bottom hole pressure (BHP) in a natural gas well is an important parameter in the effective design of well completions and artificial lifting systems. Poor estimation of this can lead to liquid loading in the wellbore and reduced efficiency of the extraction process. The complex interaction of production gas and the associated water can increase the uncertainty in pressure gradients and ultimately impact the BHP estimation. A significant body of research has explored pressure gradients in the co-current multiphase flows found in conventional gas extraction, but these are not expected to hold for the counter-current regimes present in CSG production. Therefore, this research aimed to develop a fully resolved-numerical model for the simulation of simultaneous gas and liquid transport in scenarios applicable to CSG extraction. When two-phases flow in a confined environment such as a pipe or conduit, the topology of the interface is described by commonly observed flow regimes. When the pipe is in a vertical configuration, the typical regimes include bubble, slug, churn and annular flow. The models that describe the liquidgas interactions are typically dependent on the flow regime and can significantly impact the accuracy of pressure predictions. As a result, knowledge of the flow regime is required a priori to predicting the pressure gradient. Once this has been determined, the uncertainty associated with the phase interaction models can still deteriorate the practical use of predictive tools. The rise velocity of elongated bubbles in the slug flow regime has recently been identified in the literature as impacting greatly on the estimation of liquid hold up and pressure gradients in a piping system. Understanding the behaviour of these bubbles, termed Taylor bubbles, allows operators to reduce pressure oscillations in the wellbore and more accurately forecast production over the life of the well. This work seeks to capture the behaviour of these bubbles in flow configurations applicable to CSG extraction. This involves modelling annular pipe systems at a range of inclinations as well as with fluids propagating in co-and counter-current directions. This thesis presents the development, verification and validation of a phase-field lattice Boltzmann method (PFLBM) that allows for the simulation of dynamic liquid-gas flows with density ratios on th...
