Foam Quality of Foams Formed on Capillaries and Porous Media Systems

Foams are of great importance as a result their expansive presence in everyday life—they used the food, cosmetic, and process industries, detergency, oil recovery, firefighting. There is little understanding foam formation using soft porous media terms quality formation. Interaction foams with has recently been investigated study by Arjmandi-Tash et al., where three different regimes drainage contact were observed. In this study, amount generated surfactant solutions investigated. The aim to understand produced media. effect capillary sizes arrangement on This then followed use for how surface that conditions (such concentration) have foam. blanket term bubble size, liquid volume fraction, stability fraction calculated homemade dynamic analyser, which obtain distribution along height. Soft does not influence substantially rate decay produced, however, it decreases average diameter bubbles, whilst increasing range due wide pore present analyser showed expected behaviour that, decays becomes drier, falls, therefore conductivity also decreases, indicating usefulness home-made device future investigations.
