Complex Flows

A group picture of mechanical engineering's complex flows researchers

The complex flows research supergroup has expertise in computational and experimental fluid dynamics. Common themes of their work include include turbulence, the presence of multiple phases (bubbles, drops, or particles), or the use of non-Newtonian flows. Specific research areas cover method development, bio-fluid dynamics, combustion, turbomachinery, renewable energy, environmental fluid mechanics, and marine science.

The group's goals are to develop new physical insights, predictive models, and control strategies for complex flows in natural and engineered environments. The objective of the supergroup is to facilitate collaborations and synergistic efforts among the members, particularly in student recruiting and co-advising. A student who is interested in any of the topics above (or fluid dynamics more generally) should reach out to a member of the supergroup.
