Shear Layer and Wake Characteristics of Square Cylinder in Transonic Flow
Shanghai Jiaotong Daxue xuebao, 2021 The transonic flow around a square cylinder at Ma= 0.71 and Re= 4×105 has been studied by using the scale-adaptive simulation (SAS) method, and the characteristics of separated shear layer and wake have been analyzed in depth. To validate the SAS

Mass Loss From Planetary Nebulae in Elliptical Galaxies [PDF]
, 2009 Early-type galaxies possess a dilute hot (2-10E6 K) gas that is probably the thermalized ejecta of the mass loss from evolving stars. We investigate the processes by which the mass loss from orbiting stars interacts with the stationary hot gas for the ...

Unsteady Effects of Wake on Downstream Rotor at Low Reynolds Numbers
Energies, 2022 In a compressor, the periodic wake is an inherently unsteady phenomenon that affects the downstream flow conditions and loading distribution. Thus, understanding the physical mechanisms of these unsteady effects is important for eliminating flow losses ...

Wake Component Detection in X-Band SAR Images for Ship Heading and Velocity Estimation
Remote Sensing, 2016 A new algorithm for ship wake detection is developed with the aim of ship heading and velocity estimation. It exploits the Radon transform and utilizes merit indexes in the intensity domain to validate the detected linear features as real components of ...

The Generation of Turbulence by Oscillating Structures in Superfluid Helium at Very Low Temperatures [PDF]
, 2006 The paper is concerned with the interpretation of many experiments that have been reported recently on the production of quantum turbulence by oscillating spheres, wires and grids in both 4He and 3He-B at temperatures so low that there is a negligible ...

Numerical Simulation of the Maneuvering Motion Wake of an Underwater Vehicle in Stratified Fluid
Journal of Marine Science and Engineering, 2022 When a vehicle moves underwater, disturbance is generated and a wake remains that destroys the original free surface and produces a new wake. In order to study the mechanism and characteristics of the wave-making wake generated by the maneuvering motion ...

Kelvin-Helmholtz instability of a coronal streamer
, 2013 The shear-flow-driven instability can play an important role in energy transfer processes in coronal plasma. We present for the first time the observation of a kink-like oscillation of a streamer probably caused by the streaming kinkmode Kelvin-Helmholtz

Thickness effect of Naca foils on hydrodynamic global parameters, boundary layer states and stall establishment [PDF]
, 2010 The present study investigates experimentally the hydrodynamic behavior of 2D NACA (15, 25, 35%) symmetric hydrofoils at Reynolds number 0.5 106 . A particular attention is paid on the hysteretic behavior at static stall angle and a detailed cartography

Far-Field Features of the Kelvin Wake
, 1986 The classical Kelvin wake trailing a ship advancing at constant speed in calm water is studied. In particular, asymptotic expressions for determining the far-field wake, at large distances behind the ship, are investigated numerically.

HF radar signatures of ship and submarine wakes
The Journal of Engineering, 2019 Radars operating in the HF band have been widely used to detect and track surface ships from their skin echoes; indeed, in many cases this has been the primary mission of the radar.
