Experimental Study of Supercavitation Bubble Development over Bodies in a Duct Flow
Journal of Marine Science and Engineering, 2020 Understanding the development and geometry of a supercavitation bubble is essential for the design of supercavitational vehicles as well as for prediction of bubble formation within machinery-related duct flows. The role of the cavitator (nose) of a body

Scaling of cavitation erosion progression with cavitation intensity and cavitation source [PDF]
Wear, 2012 Abstract A simple mathematical expression is presented to describe cavitation mean depth of erosion versus time for cavitating jets and ultrasonic cavitation. Following normalization with a characteristic time, t* , which occurs at 75% of the time of maximum rate of erosion, and a corresponding material characteristic mean erosion depth, h* , the ...

Performance Comparison of Bow and Stern Rudder for High‐Speed Supercavitating Vehicles
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 To predict the hydrodynamic characteristics and supercavity shape of supercavitation flows, the numerical model including VOF, cavitation model, and turbulence models is presented and validated by a well‐established empirical correlation. The numerical method is then employed to simulate the high‐speed supercavitating vehicles with two different types ...

Complexity, Volume 2020, Issue 1, 2020., 2020 Due to the complexity of the cavity/vehicle and oscillation characteristics, streamlined shape integrated design of conventional fully wetted vehicles is not suitable for supercavitating vehicles. In this paper, a set of design criteria is highlighted to optimize the length and streamlined shape of a conical section subjected to realistic design ...

Occult Infection in Aseptic Joint Loosening and the Diagnostic Role of Implant Sonication. [PDF]
Biomed Res Int, 2015 Our aim was to determine the incidence of occult infection and to examine the role of ultrasound sonication of the implants in cases of presumed aseptic loosening in a prospective trial. Joint swabs, aspirates, and deep tissue samples were obtained from around the prosthesis for routine microbiology.

Influence of attack angle on ventilated supercavitating flow at high Froude number condition
Xibei Gongye Daxue Xuebao, 2022 To study the influence of attack angle on ventilated supercavitating flow, a numerical model is established to simulate the supercavitation flow by using the inhomogeneous multiphase flow model and the SST k-ω turbulence model.

Interface Focus, 2015 Abstract We generally think of bubbles as benign and harmless and yet they can manifest the most remarkable range of physical effects. Some of those effects are the stuff of our everyday experience as in the tinkling of a brook or the sounds of breaking waves at the beach.
