MODEL REDUCTION FOR FOR TIME-CRITICAL APPLICATIONS IN AERONAUTICAL ENGINEERING

In many applications, high-fidelity time-dependent numerical simulations remain so computationally intensive that they cannot be used as often as needed, or are more often used in special circumstances than routinely. This is the case, for example, for turbulent CFD computations at high Reynolds numbers. Consequently in many engineering fields, the impact of computational sciences on time-critical operations such as design, design optimization, and control, has not yet fully materialized. For such operations, model reduction methods that can faithfully reproduce the essential features of the larger computational models at a fraction of their computational cost offer a promising alternative. This talk will present recent advances in this field and demonstrate, for the first time, the real-time performance on mobile devices such as an iPAD, an iPhone or any other smart phone of a CFD-based computational methodology for the flutter analysis of complex aircraft configurations in subsonic, transonic, and supersonic airstreams.

Speaker: Dr. Charbel Farhat and his research group develop mathematical models, advanced computational algorithms, and high-performance software for the design and analysis of complex systems in aerospace, mechanical, and naval engineering. Their current application focus is on the aerodynamics of Micro Aerial Vehicles and Formula 1 cars, ballistic fabric for lightweight shields, nonlinear aeroelasticity of fighter jets and high-altitude long endurance aircraft, underwater acoustics and imaging, and underwater implosion. Their current theoretical and computational emphases are on high-performance multi-scale modeling of multi-physics problems, and efficient model reduction for time-critical applications such as design and active control. Professor Farhat is designated by the Institute for Science Information as a highly cited researcher in engineering. He has received numerous national and international awards. He is also a Fellow of AIAA, ASME, IACM, USACM, and WIF.
