A Numerical Study of a Submerged Water Jet Impinging on a Stationary Wall
Journal of Marine Science and Engineering, 2022 The impinging jet is a classical flow model with relatively simple geometric boundary conditions, and it is widely used in marine engineering. In recent years, scholars have conducted more and more fundamental studies on impact jets, but most of the ...

Atmospheric and submerged bone cement erosion by a pulsating water jet with a straight tubular nozzle extension [PDF]
Scientific ReportsA pulsating water jet (PWJ) offers advantages over a continuous water jet, such as lower liquid volume flows and pressures for deeper cuts. However, traditional PWJ setups are unsuitable for minimally invasive surgeries due to their size.

Development of turbulence in subsonic submerged jets [PDF]
Physics Reports, 2004 Abstract The development of turbulence in subsonic submerged jets is reviewed. It is shown that the turbulence results from a strong amplification of the weak input noise that is always present in the jet nozzle exit section. At a certain distance from the nozzle the amplification becomes essentially nonlinear.

Effect of Nozzle Outlet Shape on Cavitation Behavior of Submerged High-Pressure Jet
Machines, 2021 A submerged high-pressure water jet is usually accompanied by severe cavitation phenomenon. An organ pipe nozzle can greatly improve the cavitation performance of the jet, making use of the self-excited oscillation of the flow.

Sediment Removal from Deep Reservoir Dams by Suction and Jet Flow [PDF]
E3S Web of Conferences, 2022 One method of sediment removal from dam reservoirs is the use of submerged pumps and suction mixes of sediment and water. This method is usually considered for shallow rivers but we want to adopt this method for large dams.
