Zusammenfassung: | We present an axisymmetric lattice Boltzmann model based on the Kupershtokh
et al. multiphase model that is capable of solving liquid-gas density ratios up
to $10^3$. Appropriate source terms are added to the lattice Boltzmann
evolution equation to fully recover the axisymmetric multiphase conservation
equations. We validate the model by showing that a stationary droplet obeys the
Young-Laplace law, comparing the second oscillation mode of a droplet with
respect to an analytical solution and showing correct mass conservation of a
propagating density wave. |
