Research on Cavitation Characteristics of Two-Throat Nozzle Submerged Jet
Applied Sciences, 2022 Ship fouling not only increases ship resistance and fuel consumption but is equally a type of biological invasion, which causes severe ecological damage. Submerged cavitation jet cleaning is an environmentally friendly, high-efficiency, and energy-saving

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.

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.

Bed load transport by submerged jets [PDF]
Proceedings of the National Academy of Sciences, 1979 Some similarities are presented between the bed load transport of noncohesive grains in long rivers and at a local, jet-induced scour. Experiments are described in which a submerged two-dimensional slot nozzle, inclined downward, eroded a deep sand bed.

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.
