RISResolving Pitching Airfoil Transonic Aerodynamics by Computational Fluid Dynamics Data Modeling1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A detailed numerical study of harmonically pitching airfoils of NACA00 series is presented here. Based on the analysis of the computational fluid dynamics (CFD) results, a hypothesis is made that a simple data model can ...
A Machine Learning Approach to Predicting Unsteady Transonic Flow of Pitching Airfoils1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A machine learning methodology has been proposed in this paper to study the unsteady transonic aerodynamics in the flutter regime. The methodology is based on a well-established regularization technique, and it compares ...
An Active Flow Control Approach for Spatially Growing Mixing Layer1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A control approach is proposed in this study that controls the growth of a spatially growing mixing layer in an open loop. Due to the similarity of the mixing layer dynamics in the temporal and spatial domains, the control ...
Drag Characterization Study of Variable Camber Continuous Trailing Edge Flap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A Reynolds-averaged Navier–Stokes (RANS) computational study was conducted to investigate the effect of various variable camber continuous trailing edge flap (VCCTEF) configurations on the lift and drag of a NASA generic ...
