Abstract: Some salts can inhibit bubble coalescence above a critical concentration. The initial models for prediciting the critical salt concentrations were developed based on the effects of the Gibbs-Marangoni stress and either the London-van der Waals… read more here.

Abstract: Two-dimensional base state solutions for rimming flows and their stability analysis to small axial perturbations are analyzed numerically. A thin liquid film which is uniformly covered with an insoluble surfactant flows inside a counterclockwise rotating… read more here.
