Modulation effects of submarine internal wake waves on free surface …
Jun 6, 2023 · It is shown that after the appearance of mode 0, the wake waves have an appreciable effect on the modulation of the free surface wind-wave field. However, this effect is not fixed to manifest as an enhancement of the free …
Surface Waves Induced by a Moving Submarine Model
Apr 15, 2023 · In this study, the internal and free surface wave wakes caused by a moving submarine in two layers of constant density fluid were studied numerically using the commercial software STAR-CCM+.
Investigation of internal wave wakes generated by a submerged …
Dec 15, 2022 · As the buoyancy effect on the internal wave patterns is apparent when the submerged body is located below the pycnocline, the internal wave wakes generated by submerged body at different depths below the pycnocline are investigated.
Internal waves affect naval operations in two principal areas--depth control and detection capability. The passage of large-amplitude internal waves could make submarine depth control difficult, particularly when the submarine is running quietly at low speed.
Free surface features of submarines moving underwater: Study of ...
Apr 1, 2022 · Three different phenomena are caused either directly or indirectly by surface wakes: internal waves and turbulence, Kelvin wake and Bernoulli's Hump. In this study Bernoulli's hump is the main area of focus.
From the current research status, the numerical studies have not discussed the influence of free surface waves induced by a submarine model moving at typical cruising speed on internal...
(PDF) Wake Features of Moving Submerged Bodies and Motion …
Jan 13, 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.
Study on the internal waves induced by a submerged body …
Aug 7, 2024 · This paper studies the characteristics of internal waves induced by the motion of a submerged body through a combination of experimental and numerical methods.
In this study, the internal and free surface wave wakes caused by a moving submarine in two layers of constant density fluid were studied numerically using the commercial software STAR-CCM+.
The results indicate that if the velocity of the submarine is small, the waveform results of internal waves with both the free surface and the rigid lid approximation are only V-shaped waves.
