Mobile Interfaces and Adsorbed Surfactants in Emulsions

Research goal

Coalescence and break-up of droplets governs numerous industrial processes. The current practice of predicting and modeling such systems lacks fundamental rigor, making the scale-up and scale-down procedures unreliable. The aim of this project is to develop a mesoscopic DNS framework to study droplet dynamics under turbulent conditions in surfactant laden emulsions. The results can help formulate more accurate coalescence and break-up models useful for macroscopic simulations.

Snapshots of the normalized surfactant density fields (blue-green) shown for a spinodal decomposition simulation, which shows the coarsening of droplets by coalescence (left to right). The droplet contours are shown in white over half the domain.
