Patankar group research is focused on four primary missions: First, to develop fully resolved computational fluid dynamics (CFD) techniques to simulate muscle activated movement of organisms (e.g. knifefish, zebrafish) and organs (e.g. esophagus). Second, to use theory and CFD to understand the neural control of movement, to design novel underwater vehicles, and to interrogate the evolution of fish form and function. Third, to establish the foundational science of controlling phase (anti-icing, anti-frosting, boiling, condensation, non-wetting supehydrophobic surfaces) using surface roughness and chemistry. Fourth, to establish new metrics to quantify the mileage efficiency and greenhouse emissions of automotive vehicles.

In the Classroom
Professor Patankar has taught Engineering Fluid Mechanics (ME 373) and Engineering Analysis III (EA3; Gen Eng 205-3) for undergraduates. He has 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), and on textured surfaces to tune wetting behavior.
