Abstract
- This paper analyzed colloidal characteristics of a bimodal distribution emulsion system using bulk rheological and numerical approaches. The experiment measured simple shear to confirm emulsion shear thinning and viscosity tendencies. Numerical models employed the multi-component lattice Boltzmann method to express interfacial tension, surfactant movement, and viscosity of liquid phases. Numerical models were helpful to implement interactions between two or more varied-sized liquid droplets, since they express droplet deformation and interaction forces and can also provide rheological analysis, whereas shear flow experiments cannot. In monodisperse systems (i.e., uniform droplet size), larger droplets decrease emulsion relative viscosity. However, mixture viscosity for bimodal systems (small droplets mixed with large droplets) was lower than that for the monodisperse system. The reduced viscosity was related to increased droplet deformability and decreased shear stress at the droplet surface.
