“…The conventional numerical simulation modeling of cavitation bubble collapse can be divided into macroscopic scale, microscopic scale and mesoscopic scale. The macroscopic numerical scale include the finite element method (FEM), 6 finite volume method (FVM), 7 and boundary element method (BEM). 8 However, in the simulation of multiphase flow, the macroscopic models based on the classical partial differential equation numerical simulation need to track or capture the interface.…”

Understanding the dynamic characteristic of the cavitation bubble near a solid wall is a fundamental issue for the bubble collapse application and prevention. In the present work, an improved three-dimensional multi-relaxation-time pseudopotential lattice Boltzmann model is adopted to investigate the cavitation bubble collapse near the solid wall. With respect to thermodynamic consistency, Laplace law verification, the three-dimensional pseudopotential multi-relaxation-time lattice Boltzmann model is investigated. By the theoretical analysis, it is proved that the model can be regarded as a solver of the Rayleigh–Plesset equation, and confirmed by comparing the results of the lattice Boltzmann simulation and the Rayleigh–Plesset equation calculation for the case of cavitation bubble collapse in the infinite medium field. The bubble collapse near the solid wall is modeled using the improved pseudopotential multi-relaxation-time lattice Boltzmann model. We find the lattice Boltzmann simulation and the experimental results have the same dynamic process by comparing the bubble profiles evolution. Form the pressure field and the velocity field evolution it is found that the tapered higher pressure region formed near the top of the bubble is a crucial driving force inducing the bubble collapse. This exploratory research demonstrates that the lattice Boltzmann method is an alternative tool for the study of the interaction between collapsing cavitation bubble and matter.

“…In present 2-D simulation, the Rayleigh-Plesset equation should be revised as [69,70] , (23) where Rbound is the size of the square domain, R is the radius of the 2-D bubble, Pvapor is the pressure inside the gas bubble (simplified as the vapor pressure), and Pbound is the…”

“…To solve the multiphase cavitation problem with conventional computational fluid dynamics (CFD) methods, both a Navier-Stokes equation and interface equation (such as volume of fluid [20] or level set method [21]) have to be solved simultaneously. Various numerical techniques, including finite element methods [22], finite volume methods [23][24][25][26], diffuse interface models [27], and two- [28,29] and three-dimensional [30,31] boundary element methods, have been employed to simulate microscopic bubble behavior and macroscopic cavitation flows (e.g., cavitation jets and hydrofoil cavitation). However, even with simplified physical models (full cavitation model [32], Schner-Sauer model [33], and Zwart-Gerber-Belamri model [34]), which help to describe the liquid-vapor phase change, cavitation simulation using partial-differential-equation-based numerical methods is computationally demanding.…”

This work serves as an important extension of previous work on cavitation simulation [Sukop and Or, Phys. Rev. E 71, 046703 (2005)10.1103/PhysRevE.71.046703]. A modified Shan-Chen single-component multiphase lattice Boltzmann method is used to simulate two different heterogeneous cavitation nucleation mechanisms, the free gas bubble model and the crevice nucleation model. Improvements include the use of a real-gas equation of state, a redefined effective mass function, and the exact difference method forcing scheme. As a result, much larger density ratios, better thermodynamic consistency, and improved numerical accuracy are achieved. In addition, the crevice nucleation model is numerically investigated using the lattice Boltzmann method. The simulations show excellent qualitative and quantitative agreement with the heterogeneous nucleation theories.
