Research Interests

Patankar group research is focused on three primary missions: First, to develop fully resolved computational fluid dynamics (CFD) techniques for fluid-structure interaction problems. Second, to use theory and CFD to understand organ physiology (esophagus, aorta, lungs), and to bring mechanics-based analyses and diagnostic tools into clinical practice. Third, to establish the foundational science of controlling phase (anti-icing, anti-frosting, boiling, condensation, non-wetting supehydrophobic surfaces) using surface roughness and chemistry.

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.
