Some Characteristics of a Partially Cavitating Hydrofoil

Journal of the Society of Naval Architects of Japan, 1972
Cavitation is one of the most important in the field of ship hydrodynamics. It is almost unavoidable phenomena for heavily loaded screw propellers. In spite of many investigations that have been carried out for a long time, there are many problems left to be pursued. Especially quantitative explanations of cavitation are lacking or left vague.

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

The Cavitation Characteristics of Two-Dimensional Hydrofoils

Journal of the Society of Naval Architects of Japan, 1979
In this paper the authors describe investigations of the detailed cavitation structure, those are cavity length and its fluctuation, cavity shape and volume, void ratio in the cavity and velocity and pressure distribution around a cavitated foil. The following six foil sections were tested : Non-burst type : NACA 0015, NACA 16-015, NACA 4415Burst type :

Turbulence Characteristics of Cavitating Fluid in Orifice

Journal of Harbin University of Science and Technology, 2021
In order to improve the hydrodynamic cavitation intensity and obtain the cavitation law of orifice plate cavitator, Considering the influence of fluctuation on cavitation model, fluctuation influence factors were introduced. We obtained the fluid fluctuation cavitation model, using the method of multiphase flow to get mass transfer rate and turbulence ...
