Research on cavity collapse characteristics during high-speed water-exit of the supercavitating projectile

The Physics of Fluids, 2023
During high-speed water-exit of the supercavitating projectile, the cavity interacts with the free surface and collapses, with instantaneous high collapse pressure impacting on the projectile.

Vessel growth and collapsible pressure-area relationship

American Journal of Physiology-Heart and Circulatory Physiology, 1997
The role that the pattern of vessel wall growth plays in determining pressure-lumen area (P-A) and pressure-compliance curves was examined. A P-A vessel model was developed that encompasses the complete range of pressure, including negative values, and accounts for size given the fixed length, nonlinear elastic wall properties, constant wall area, and

Computing Collapse Pressure for Coiled Tubing

SPE Gulf Coast Section/ICoTA North American Coiled Tubing Roundtable, 1996
Abstract Other published literature discusses collapse pressure (CP) for round tubing,1 and proposes one collapse pressure (CP) expression for any OD-to-wall (D/t) ratio. This expression is easily solved and can be used with all units: US, metric, etc. CP for oval tubing was a subject of another paper.2 This paper presents

Pressure-Flow Relationships in Collapsible Tubes

IEEE Transactions on Biomedical Engineering, 1969
The pressure-flow characteristic of a short collapsible tube held open at its ends and inserted between two constrictions was investigated as a function of flow for different external pressures and downstream constrictions. Taking the upstream and downstream pressure and the flow through the tube as coordinates, a surface can be determined from which ...

Collapse pressures for rhombic plates

International Journal of Mechanical Sciences, 2000
In earlier works of the author upper bound estimates for the collapse of clamped or simply-supported regular polygonal plates under uniform pressure had been derived for rigid-plastic materials that satisfy the square Johansen yield criterion. The present paper adopts a similar technique and desribes the collapse mechanism more precisely, in particular

Pressure-Flow Characteristics of Collapsible Tubes

Advances in Bioengineering, 1994
Abstract An experimental investigation has been made on the pressure-flow behaviour of collapsible tubes, particularly the effects due to upstream pressure and downstream reservoir-head. These and other experimental parameters were systematically varied to determined the pressure-drop versus flow characteristics.

Pressure/flow relationships in collapsible tubes: effects of upstream pressure fluctuations

Medical & Biological Engineering & Computing, 1991
An experimental investigation has been made on the pressure/flow behaviour of a collapsible tube. Of particular interest are the effects of upstream pressure fluctuations on the mean pressure/flow relationships. These mean pressure/flow relationships were found to exhibit features generally similar to the steady-flow situation, including flow ...

Experimental Investigation of Cavity Collapse Pressures

The Journal of the Acoustical Society of America, 1959
Single, hemispherical spark cavities were created in water at the pressure end of a Duralumin pressure bar. At the collapse of such a cavity, a transient stress pulse (∼20 μsec duration) is propagated along the bar which is detected by an X-cut circular disk of quartz of the same diameter as the pressure bar.
