摘要: A moving circular wave front forms after a small droplet of aqueous surfactant solution is deposited on thin layer. The time evolution the radius was monitored. Surfactants different solubility were used at concentrations above CMC. It shown that proceeds in two stages: rapid first stage, which followed by slower second stage. substantially depends solubility. An exact for deduced case insoluble surfactants. qualitative theory developed to account influence motion. Our experimental observations are good agreement with predictions.
