A review of Backward-Facing Step (BFS) flow mechanisms, heat transfer and control
Abstract Backward-Facing Step (BFS) flow is one representative model for separation flows,
which can be widely seen in aerodynamic flows (airfoil, spoiler, high attack angle process) …

Recent developments in the prediction and control of aerodynamic noise from high-speed trains
At speeds above 300–350 km/h, the main source of noise from trains is the aerodynamic
noise caused by the air flow over the train structure. The sound level increases with train …

Conditions for validity of mean flow stability analysis
This article provides theoretical conditions for the use and meaning of a stability analysis
around a mean flow. As such, it may be considered as an extension of the works by McKeon …

Closed-loop separation control using machine learning
We present the first closed-loop separation control experiment using a novel, model-free
strategy based on genetic programming, which we call 'machine learning control'. The goal …

Blood flow and coherent vortices in the normal and aneurysmatic aortas: a fluid dynamical approach to intra-luminal thrombus formation
Abdominal aortic aneurysms (AAAs) are frequently characterized by the development of an
intra-luminal thrombus (ILT), which is known to have multiple biochemical and …
