Abstract: 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 of the submerged body.

4 天之前 · The team focused on studying the impact of Kelvin wake, a V-shaped wave pattern created by submarines or other ships while sailing. The waveforms are at a consistent angle due to the interaction ...

2021年8月1日 · Here, we demonstrate the feasibility of using visible-light polarization imaging to observe submarine wakes. The key links in the imagine chain are considered separately.

2024年3月15日 · Wakes produced by underwater vehicles, particularly submarines, in density-stratified fluids play a pivotal role across military, academic, and engineering domains.

2020年1月13日 · In order to extract the submarine’s location and velocity information effectively from the wake photoelectric images, we investigate the relationship between the motion state of moving...

Equatioi's have been developed for predicting submarine wake dimen- sions as a function of submarine velocity, initial wake size, ambient stratification, and time after submarine passage.

2023年11月13日 · The internal and surface wakes can be generated by the moving submerged vehicle in the stratified ocean which density or temperature must be changed continuously or discontinuously with the depth. These wake characteristics play an important role in non-acoustic submarine detection and fundamental stratified flow physics [1,2,3].

In this paper, the generation and evolution of wave mak-ing on the pycnocline interface and free surface produced by a horizontally moving submerged vehicle in a two-layer ocean of finite depth were analyzed by simulations and experiments. The efect of velocity on the wake wave char-acteristics is the main emphasis of our research.

2024年7月1日 · The motion of charged seawater in a submarine wake, which is affected by the variance in the ion mass and the presence of a background geomagnetic field, results in a consequential wake magnetic field. The magnetic field is critical for the detection and monitoring of underwater targets.

A submarine leaves a detectable wake trail as it breaks the water’s surface Professor Monty and his team are developing the underlying theory that will build the foundations for systems that will improve a submarine operator’s ability to reduce the detectability of its wake.
