Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Investigations of data-driven closure for subgrid-scale stress in large-eddy simulation

The Physics of Fluids, 2018
Data-driven machine learning algorithms, random forests and artificial neural network (ANN), are used to establish the subgrid-scale (SGS) model for large-eddy simulation. A total of 30 flow variables are examined as the potential input features.

Large-eddy simulation of flow over an axisymmetric body of revolution

Journal of Fluid Mechanics, 2018
Wall-resolved large-eddy simulation (LES) is used to simulate flow over an axisymmetric body of revolution at a Reynolds number, $Re=1.1\times 10^{6}$ , based on the free-stream velocity and the length of the body.

Wall-Modeled Large-Eddy Simulation of Transonic Airfoil Buffet at High Reynolds Number

AIAA Journal, 2016
In this study, wall-modeled large-eddy simulation of transonic buffet phenomena over the OAT15A supercritical airfoil at two different Mach number conditions (nonbuffet M∞=0.715 and buffet M∞=0.73 conditions) at high Reynolds number Rec=3.0×106 is ...
