The stability of laminar symmetric separated wakes [PDF]

open access: yes, 2005
Time-dependent computations of the two-dimensional incompressible uniform-velocity laminar flow past a normal flat plate (of unit half-width) in a channel are presented.

A numerical study of an inline oscillating cylinder in a free stream [PDF]

open access: yes, 2011
Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

Parameter retrieval of aircraft wake vortex based on its max–min distribution of Doppler velocities measured by a Lidar

open access: yesThe Journal of Engineering, 2019
Aircraft wake vortex is a sort of turbulence generated by a flying aircraft. It has attracted much attention in aviation safety area because it may cause a following aircraft to roll out of control.

Response of Viscoelastic Turbulent Pipeflow Past Square Bar Roughness: The Effect on Mean Flow

open access: yesComputation, 2021
The influence of viscoelastic polymer additives on response and recovery of turbulent pipeflow over square bar roughness elements was examined using Direct Numerical Simulations at a Reynolds number of 5×103.

The Effects of Flexible Cylinder Structural Dynamics to the near Wake Turbulence

open access: yesFluids, 2023
The utilization of a rigid and projecting surface, coupled with an agitator and vortex generator, frequently results in the dissipation of more energy than the production of turbulence that meets the required criteria.

HF radar signatures of ship and submarine wakes

open access: yesThe 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.

I do, I understand: engaging distance and campus students in sustainability through active learning

open access: yesResearch in Learning Technology, 2023
Distance online learning connects students to education opportunities without having to be present at the institution offering the learning module. This case study involved development of a dual on-campus and distance course into a fully online course ...

Multitarget Multisensor Trackingin the Presence of Wakes [PDF]

open access: yes, 2010
TARGET tracking is an essential requirement for surveillance and control systems to interpret the environment. This environment may contain multiple targets, and the environmental information may be obtained by multiple sensors in a multitarget ...
