Research Interests
My research centers on computational fluid dynamics, spanning a diverse and cross-
disciplinary range of topics in biofluids, hydraulics, environmental fluid mechanics, chaotic advection,
and large-scale transport in geophysical flows. A major thrust of my research group is the development of
advanced numerical algorithms for simulating turbulent flows in real-life natural and man-made
environments using statistical turbulence models that directly resolve the dynamics of unsteady, coherent
structures. These algorithms are applied to simulate sediment transport by large-scale vortices in the
vicinity of bridge foundations, turbulent flows in hydraulic machinery, stratified and buoyancy dominated
flows in lakes and reservoirs, and turbulent mixing in water and wastewater treatment mixing devices and
in water storage facilities. My research group has also developed a novel computational technique for
simulating flows in domains with 3D, arbitrarily complex, flexible immersed boundaries. This technique is
being used to tackle computationally problems that reside at the interface between fluid mechanics with
biology and bioengineering. Ongoing projects include the simulation of various cardiovascular flows, with
emphasis on biomedical devices and virtual surgery, hydrodynamics of aquatic locomotion, and
hydrodynamic signal detection by planktonic organisms. Another area of active research is the experimental
and computational investigation of Lagrangian coherent structure dynamics in chaotically advected flows as
well as in large scale geophysical and environmental flows.
Dr. Sotiropoulos conducts his research at the St. Anthony Falls
Laboratory, the National Center for Earth-surface Dynamics, and
the Computational Hydrodynamics and Biofluids Laboratory in
Minnesota.
