New models are developed for the viscosity of concentrated emulsions taking into consideration the effects of interfacial rheology and Marangoni phenomenon. The interface is assumed to be viscous with non-zero surface–shear and surface-dilational viscosities. The Marangoni effect is accounted for through non-zero Gibbs elasticity of the interface. The experimental viscosity data for a number of emulsion systems are interpreted in terms of the proposed models.
Graphical abstractThe plot shows relative viscosity as a function of the interfacial mobility parameter, predicted by the proposed models at a fixed volume fraction of dispersed phase (ϕ = 0.50).Figure optionsDownload full-size imageDownload high-quality image (94 K)Download as PowerPoint slideResearch highlights► Influence of interfacial rheology and Marangoni phenomenon on the relative viscosity of concentrated emulsions is considered. ► New models are developed for emulsion viscosity taking into consideration the effects of interfacial rheology and Marangoni phenomenon. ► Experimental viscosity data for emulsions are interpreted in terms of the proposed models.
