Molecular Dynamics Simulation of the Synergistic Effect of Alkali/Surfactant/Polymer on the Formation and Stabilization of Water-Based Foam Systems

“…Foam is a typical thermodynamically unstable system; as soon as it is created, it is accompanied by evolution processes such as liquid drainage, bubble coalescence, and the rupture of the foam films. These processes are determined by the characteristics of the foam film and also affect the stability of the foam [ 7 , 8 ]. At present, the recognized foam decay and collapse mechanisms can be divided into foam drainage, gas diffusion, and foam coalescence.…”

Random Packing Performance in Continuous Foam Fractionation

“…The bubbles inside the foam phase rise along the vertical axis of the column, meanwhile, the interstitial liquid drains out of the foam through an intricate network comprising numerous plateau borders and nodes 12, 13. However, this network results in serious resistance for foam drainage 14. Foam drainage always reaches its equilibrium at a higher liquid holdup.…”
