Our research centers on the fluid dynamics of dispersed multiphase flows, complex fluids, and interfacial phenomena. We study these topics through a combination of fully-resolved simulations and mathematical analysis, and develop simple experiments when modelling is impossible or inaccurate.
A primary focus of our research is the interaction of particles (including "fluid" particles such as drops or bubbles) with hydrodynamic flows and fluid interfaces. We are typically interested in particle-scale phenomena; this point of view allows great insights into macroscopic transport phenomena, rheology and self-assembly.
Current projects focus on:
- capillary self-assembly of complex-shaped colloids at fluid interfaces
- elastocapillary effects with drops
- rheology of non-colloidal fibers
Application of fluid mechanics principles to materials science and engineering
Fluid mechanics is ubiquitous in the manufacturing of advanced materials. Producing polymer composites, for instance, requires processing polymer melts, containing colloids, nanoparticles, or nanofibers, at very high shear rates. Understanding the flow phenomena occurring during processing of these materials enables one to manufacture high-quality materials by faster, and cheaper, routes.
New applications are emerging. The oil, food, health, personal care and plastics industries are interested interested in developing soft matter composites made by dispersing discrete elements in a fluid matrix; capsules can be produced by adsorbing particles at the interfaces of drops (see pictures below); fluids and interfaces are used in the convective assembly technique (a modern version of dip coating) to make photonic crystals and new-generation batteries. Chemistry, while important, cannot explain the formation of many new advanced materials, which often form under strongly non-equilibrium phenomena.
Queen Mary has a long tradition in materials science. We are currently establishing collaborations with colleagues at Queen Mary to develop technologies that exploit fluid flow and capillarity in the fields of advanced functional materials and biomaterials.
