Current Research:
My research focuses on investigating the interaction forces between fluid and solid particles at small length scales. Using insights gained from highly-resolved lattice Boltmann method (LBM) simulations, I seek to develop fluid-particle drag models that can be applied as constitutive closures in larger-scale simulations of fluidized beds in order to improve our ability to understand the complex dynamics observed in these systems. Specifically, using these direct numerical simulation (DNS) techniques, I seek to better understand the role that a particle's inertia relative to the viscosity of a fluid plays in the drag force experienced by a particle. Furthermore, I study the effect that inhomogeneities in the distribution of particles has on the drag force experienced by a fluid passing by these particles. My goal is to demonstrate that by accounting for these different system characteristics, my new drag model provides a significant improvement in predicting fluidization behavior over prior constitutive relations.

Current Research:
In my research, I aim to understand the fundamental physics underlying multiphase flows in order to enable optimal design and operation of processes in industry and nature relevant to energy, food and pharmaceutical production as well as waste management. I am currently working to understand the effects of liquid bridging and other interparticle forces on hydrodynamics in fluidized beds. I am using small-scale models to understand the various effects of wetting conditions on flow and the salient non-dimensional numbers in characterizing the flow. I am coarse-graining these simulations to achieve accurate industrial-scale models which account for the effect of wetness on gas-solid flows. I have a background in using magnetic resonance imaging (MRI) to study detailed hydrodynamics in multiphase flow systems, and I intend to continue this research in the future to understand the effects of interparticle forces on multiphase flows on an experimental level.
