Neural-Network and Reduced-order Modeling Workflows for AI-Driven CFD: Fast Response Surfaces, Reduced Dynamics and Jet in Cross-flow Examples
Kaku E. Eduku, Pavel P. Popov, Gustaaf Jacobs
Highly resolved computational fluid dynamics (CFD) simulations are essential for design but too expensive for dense design-space sampling. This chapter presents an AI-driven CFD wo…
Characteristic Sensitivity Ensembles for Inference of Hidden Dynamics from Marginal Observations
Qi Wang, Gustaaf Jacobs
A framework is developed for the inference of dynamics described by a generalized system of ordinary differential equations. A stochastic gradient method is coined that infers dyna…
Robust Spectral Solver for High-Fidelity Investigations of Aerospike Nozzle Flow Dynamics
Zachary Pyle, Gustaaf B. Jacobs
A spectral element solver is developed for the high-fidelity simulation of the unsteady flow over an aerospike nozzle. The Navier-Stokes solver is a kinetic-energy-preserving, disc…
The Footprint of Laminar Separation on a Wall-Bounded Wing Section at Transitional Reynolds Numbers
Charles Klewicki, Bjoern F. Klose, Gustaaf B. Jacobs +1
When a chordwise Reynolds number (Re) falls below about the performance of wings and aerodynamic sections become sensitive to viscous phenomena, including boundary layer sep…
