Kelvin–Froude wake patterns of a traveling pressure disturbance [PDF]
European Journal of Mechanics - B/Fluids, 2021 17 pages, 8 Figures. Generality of results is illustrated via connections to linear response theory and Fourier-Kochin representation of the wake. Extra Figure and references added. Results are unchanged.

Wake Features of Moving Submerged Bodies and Motion State Inversion of Submarines
IEEE Access, 2020 The interaction between a moving submerged body and a homogeneous/stratified fluid generates a Bernoulli hump, a Kelvin wake, and an internal wake on the water surface. The height distribution of wakes is directly related to the location and motion state

A Novel Data-Driven Scheme for the Ship Wake Identification on the 2-D Dynamic Sea Surface
IEEE Access, 2020 Because the ship wake spreads into an area much larger than that of the ship hull in the sea surface, it has been widely used in the ship detection. However, due to the complex sea wave motion and the high sea state, the ship wake detection is still a ...

On self-sustained oscillations in two-dimensional compressible flow over rectangular cavities [PDF]
, 2002 Numerical simulations are used to investigate the resonant instabilities in two-dimensional flow past an open cavity. The compressible Navier–Stokes equations are solved directly (no turbulence model) for cavities with laminar boundary layers upstream ...

Baroclinic geostrophic adjustment in a rotating circular basin [PDF]
, 2004 Baroclinic geostrophic adjustment in a rotating circular basin is investigated in a laboratory study. The adjustment process consists of a linear phase before advective and dissipative effects dominate the response for longer time. This work describes in

Nonlinear Ship Wake Detection in SAR Images Based on Electromagnetic Scattering Model and YOLOv5
Remote Sensing, 2022 Traditional wake detection methods have been successfully applied to the detection of a simple linear ship wake. However, they cannot effectively detect nonlinear wake and weak wake under high sea state conditions, whereas the deep-learning-based ...

Transition models for turbomachinery boundary layer flows : a review [PDF]
, 2017 Current models for transition in turbomachinery boundary layer flows are reviewed. The basic physical mechanisms of transition processes and the way these processes are expressed by model ingredients are discussed.
