Effect of Cavitation on Vortex Dynamics in a Submerged Laminar Jet

The effects of cavitation on vortex dynamics in a submerged, two-dimensional, planar laminar forced jet were studied numerically. A locally homogeneous cavitation model that accounts for nonlinear bubble dynamics and bubble/bubble interactions within spherical bubble clusters was employed. The effects of varying key  ow and cavitation model parameters on  ow/cavitation interactions were inves...

Prevention of tissue damage by water jet during cavitation

Cavitation bubbles accompany explosive vaporization of water following pulsed energy deposition in liquid media. Bubbles collapsing at the tip of a surgical endoprobe produce a powerful and damaging water jet propagating forward in the axial direction of the probe. We studied interaction of such jet with tissue using fast flash photography and modeled the flow dynamics using a two-dimensional R...

An energy balance of high-speed abrasive water jet erosion

High-speed abrasive water jetting is an alternative tool for machining engineering materials. The energy dissipation processes involved in this erosion process have not been investigated systematically. In this paper, a model is developed to calculate the energy dissipation in workpieces eroded by abrasive water jets. By introducing an energy dissipation function ÷(Ö), the model enables the est...

The Volume Factor in Cavitation Erosion

Use of jet cavitation, however, occurs through an exit nozzle whose diameter can be changed, thereby changing volume with changing velocity. The results of such a change is shown to tie cavitation damage more powerfully to volume flow than to velocity. A specific example is in cavitation erosion of a high strength igneous rock which remained virtually undamaged at 70 MPa driving pressure but wa...

Comparison of cavitation erosion rate with liquid impingement erosion rate

Both cavitation erosion and liquid impingement erosion are phenomena that can cause pipe wall thinning in power plants. The Code for Power Generation Facilities, Rules on Pipe Wall Thinning Management, was published by the JSME (Japan Society of Mechanical Engineers) in 2005. The code says that cavitation erosion shall be prevented either in the design stage or by daily inspection. On the other...
