Description
<p> This paper experimentally identified evolution process of residual foams on surfactant surfaces via coalescence, clustering and collapsing behaviors. We found the foam size spectrum has two predominant peaks for foams with/without coalescence. The fine foams are agglutinated to form clusters, while larger coalescent foams repeat coalescing to survive for long time in the diffusion process. The clustering process affect life time of the residual foams, which is statistically modeled in this paper.</p>
