Research description

Coalescence and break-up are fundamental to many applications dealing with emulsions and dispersion. However, their existing macroscopic description in terms of kernels relies heavily on empiricism. My research involves numerical study of coalescence and break-up of these dispersed systems under the influence of turbulence. An important aspect is the inclusion of surfactant effects - considering most industrial systems are not pure. Their effect on transport, both in the bulk and across interfaces, has to be accounted for. My aim is to develop a numerical framework that benefits both from the automatic interface tracking of Lattice-Boltzmann techniques and the facilitated surfactant tracking of the Volume of Fluid Method - with results tranferrable to industries. I will also investigate the effect of swarms on the hydrodynamics, the change in collision mechanisms with changes in flow around colliding particles in dense particle neighborhoods, and their effect on shear and eddy interactions during break-up.
