This industrial Partnership Programme aims at understanding the rheology of complex emulsions and their stability under flow. While there is much empirical knowledge about emulsion rheology and stability, the microscopic physical mechanisms that govern emulsion behaviour are still poorly understood, in particular for emulsions with a complexity that goes beyond the standard oil/water/surfactant systems. This lack of understanding greatly hampers the rational design of emulsion-based products and processes. In this project we developed novel tools to study the flow and stability of emulsions, and used these to obtain a more detailed understanding.
