Models and solvers for gas-liquid systems

Models for disperse gas-liquid systems are implemented in the polydisperseBubbleFoam solver, which implements the algorithm discussed in the article of Heylmun et al. (2019) [J.C. Heylmun, B. Kong, A. Passalacqua, R.O. Fox, A quadrature-based moment method for polydisperse bubbly flows, Computer Physics Communications. (2019). doi:10.1016/j.cpc.2019.06.005].
