Soil Erosion by a Continuous Water Jet

Soils and Foundations, 2002
ABSTRACT This article presents an experimental investigation on the erosion of soils using a continuous water jet. The experimental work shows the erosive behavior of the water jet and studies the different effects of its impact on the soil. The study presents empirical relations for the volume of soil cut, the jet diameter and its expansion with the

Numerical Investigation of Jet Interaction for Missile with Continuous Type Side Jet Thruster [PDF]

International Journal of Aeronautical and Space Sciences, 2015
A continuous type side jet controller which has four nozzles with thrust control devices was considered. It is deployed to a missile for high maneuverability and fast controllability in the terminal guidance phase. However, it causes more complex aerodynamic jet interactions between the side jet and the supersonic free stream than does the conventional

The quasi-continuous exhaust regime in JET

Nuclear Fusion
The quasi-continuous exhaust (QCE) regime is a regime that is naturally type-I ELM-free. It combines the high density at the plasma edge needed for power exhaust with the high normalised energy confinement typical for H-mode operation.

Application Research of Flow Control Using Co-flow Jet on a Vertical Tail

Hangkong gongcheng jinzhan, 2022
The aerodynamic characteristics of the vertical tail of an aircraft are directly related to the size and weight of the vertical tail. Increasing the lift force of the vertical tail using flow control can further reduce the size of the vertical tail,which

Synthetic jets at large Reynolds number and comparison to continuous jets [PDF]

15th AIAA Computational Fluid Dynamics Conference, 2001
Experimental measurements and flow visualization of synthetic jets and similar continuous jets are described. The dimensionless stroke length necessary to form a 2-D synthetic jet is between 5 and 10, with wider-nozzle jets consistently requiring a smaller value.
