Abstract:
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 including aeronautics, the impact of computational sciences on time-critical operations such as design, design optimization, control, and flight test has not yet fully materialized. For these operations, reduced order models that can faithfully reproduce the essential features of the larger computational models at a fraction of their computational cost offer a promising alternative. This presentation will cover recent advances in this field. It will also demonstrate real-time performance on mobile devices of a CFD-based computational methodology for assisting flutter flight-testing and the aerodynamic design of a Formula 1 car.
