Research projects

Drag reduction within particle-laden turbulent channel flows
We embed inertial particles within a turbulent channel flow and show the ability to destroy vortical structures and augment the mass flow rate within the channel to achieve drag reduction.
Volume-Filtered Immersed Boundary method
We provide an updated immersed boundary formulation for multiphase flows that is based on the concept of volume filtering which is physically and mathematically rigorous.
