Biography
Dr. Sankar is a Regents Professor in the Guggenheim School of Aerospace Engineering at the Georgia Institute of Technology. As Director of the School's Computational Fluid Dynamics Lab, he leads a research and education program focused on the modeling and simulation of unsteady viscous flow around aircraft, helicopters, horizontal axis wind turbines, and turbo-machinery components. As the Associate Chair of the Undergraduate Programs, he coordinates undergraduate curriculum related activities. He teaches undergraduate and graduate level courses in the areas of aerodynamics, helicopter theory, wind energy, aerodynamic design, and computational aerodynamics.
Dr. Sankar is the author or co-author of more than more than 300 technical publications in the fields of spatially and temporally high order algorithms, 3-D unsteady transonic flow over aircraft configurations, helicopter aeromechanics, compressor stall and surge, wind energy, and aerodynamic design. He is an AIAA Fellow, and a member of the American Helicopter Society, American Society of Engineering Educators, and the American Society of Mechanical Engineers.
Research
Computational fluid dynamics, with applications in the following areas:
- Physics based modeling of axial and centrifugal compressor aerodynamics, and the control of compressor stall and surge phenomena
- Physics based modeling of horizontal axis wind turbines for the prediction of wind turbine performance and associated aeroelastic phenomena
- Multi-scale modeling of active and passive flow control devices for lift enhancement and drag reduction.
- Multidisciplinary approaches combining structural, aeroelastic, aerodynamic and aeroacoustic analyses for modeling and designing helicopters
