Query: Pseudopotential MRT lattice Boltzmann model for cavitation bubble
  collapse with high density ratio   The dynamics of the cavitation bubble collapse is a fundamental issue for the
bubble collapse application and prevention. In present work, the modified
forcing scheme for the pseudopotential multi-relaxation-time lattice Boltzmann
model developed by Li Q. et al. is adopted to develop a cavitation bubble
collapse model. In the respects of coexistence curves and Laplace law
verification, the improved pseudopotential multi-relaxation-time lattice
Boltzmann model is investigated. The independence between the kinematic
viscosity and the thermodynamic consistency, surface tension is founded. By
homogeneous and heterogeneous cavitation simulation, the capability of the
present model to describe the cavitation bubble development as well as the
cavitation inception is verified. The bubble collapse between two parallel
walls is simulated. The dynamic process of collapsing bubble is consistent with
the results from experiments and simulations by other numerical method. It is
demonstrated that the present pseudopotential multi-relaxation-time lattice
Boltzmann model is available and efficient, and the lattice Boltzmann method is
an alternative tool for collapsing bubble modeling.
