Research: Computational and Theoretical fluid dynamics
Prof. Patankar specializes in fast and efficient algorithms for
fully resolved simulation of immersed bodies in fluids. His techniques
are applicable at varying length scales ranging from Brownian systems
to high Reynolds number flows. The immersed bodies can be rigid
particles or freely swimming/flying bodies. Some application areas
he is interested in are: fundamentals of aquatic locomotion and
aerial flight, evolution of fish form and function, development
of artificial evolution computational tool, animation, active mechanics
of intracellular processes, sediment transport in geomorphic processes,
and dynamics of sport balls.
Other areas of research include studying the Lotus effect and
its application to self-cleaning surfaces, low drag and slip near
hydrophobic surfaces, and electrohydrodynamic flows and instabilities
in microfluidic or nanoscale devices.
In the classroom
Prof. Patankar has taught Engineering Fluid Mechanics (ME 373)
and Engineering Analysis III (EA3; Gen Eng 205-3) for undergraduates.
He will lead the EA3 course beginning from Spring 2008. He has developed
the following graduate courses: Introduction to
CFD (ME 423), Advanced Topics in CFD (ME 424), and Design and Analysis
of Microfluidic Systems (ME 421). His future course development
effort will specifically focus on the hydrodynamics of aquatic locomotion
in the broad context of biology, evolution, neuromechanical modeling,
underwater vehicle design, and animation. This effort will be undertaken
in collaboration with Prof. Malcolm MacIver.
