On the application of incomplete FWH surfaces for aeroacoustic predictions
Tulio Ricciardi, William Wolf, Philippe Spalart
This work is motivated by CFD simulations from a realistic landing gear performed modeling only the half bottom of the aircraft fuselage [15]. Hence, in this previous analysis, the…
Extremum seeking control applied to airfoil trailing-edge noise suppression
Tarcísio Costa Déda Oliveira, William Roberto Wolf
Extremum seeking control (ESC) and its slope seeking generalization are applied in a high-fidelity flow simulation framework for reduction of acoustic noise generated by a NACA0012…
Data-Driven Closure of Projection-Based Reduced Order Models for Unsteady Compressible Flows
Victor Zucatti, William Wolf
A data-driven closure modeling based on proper orthogonal decomposition (POD) temporal modes is used to obtain stable and accurate reduced order models (ROMs) of unsteady compressi…
On Secondary Tones Arising in Trailing-Edge Noise at Moderate Reynolds Numbers
Tulio R. Ricciardi, Walter Arias-Ramirez, William R. Wolf
Direct numerical simulations are carried out to investigate the flow features responsible for secondary tones arising in trailing-edge noise at moderate Reynolds numbers. Simulatio…
Active Flow Control for Drag Reduction of a Plunging Airfoil under Deep Dynamic Stall
Brener D'Lélis Oliveira Ramos, William Roberto Wolf, Chi-An Yeh +1
High-fidelity simulations are performed to study active flow control techniques for alleviating deep dynamic stall of a SD7003 airfoil in plunging motion. The flow Reynolds number…
Construction of Reduced Order Models for Fluid Flows Using Deep Feedforward Neural Networks
Hugo F. S. Lui, William R. Wolf
We present a numerical methodology for construction of reduced order models, ROMs, of fluid flows through the combination of flow modal decomposition and regression analysis. Spect…
