Abstract
A novel numerical method for simulating liquid foam decay has been developed. This method is based on a phase-field model and captures gas pressure inside the bubbles. It employs an algorithm that includes the spontaneous rupture of foam separating films and coalescence of bubbles. We found that the microstructure evolution in liquid foam in the dry foam limit is predicted. The numerical results demonstrate that the foam ageing dynamics are mapped for the decay process due to successive coalescence events. Moreover, the method is well suited for large-scale microstructure simulations. This allows the investigation of statistical properties of foams, based on the structures’ characteristics at the bubble scale. In summary, the method is effective to gain insight into the impact of fundamental factors controlling the evolution and dynamics of decaying liquid foam.
