Dynamic meshing at phase interface

Scotia

Hello, I'm hoping someone out there with more expertise than me can help out. As my undergraduate thesis I am modelling the generation of micro water droplets in a t-junction (200 micro newton square channel with a 50 micro newton diameter water inlet). I have managed to create this model and am now in the process of refining the model. My main aim at the moment is to refine the interface between the water and cross flowing oil however as the interface region is changing throughout the simulation, therefore the region that requires refinement is constantly moving. Is such a dynamic mesh refinement process possible using FLUENT and if so can someone point me in the right direction?

Any help will be greatly appreciated.
