ON THE COAGULATION AND SIZE DISTRIBUTION OF PRESSURE CONFINED CORES [PDF]
The Astrophysical Journal, 2013 Observations of the Pipe Nebula have led to the discovery of dense starless cores. The mass of most cores is too small for their self gravity to hold them together. Instead, they are thought to be pressure confined. The observed dense cores' mass function (CMF) matches well with the initial mass function (IMF) of stars in young clusters.

Morphology of prestellar cores in pressure-confined filaments [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2018 ABSTRACT Observations of prestellar cores in star-forming filaments show two distinct morphologies. While molecular line measurements often show broad cores, submillimetre continuum observations predominantly display pinched cores compared to the bulk of the filament gas.

Acoustic waves in granular packings at low confinement pressure [PDF]
Review of Scientific Instruments, 2020 Elastic properties of a granular packing show a nonlinear behavior determined by its discrete structure and nonlinear inter-grain force laws. Acoustic waves show a transition from constant, pressure-dependent sound speed to a shock-wave-like behavior with an amplitude-determined propagation speed.

Effects of Confinement and Pressure on the Vibrational Behavior of Nano-Confined Propane
The Journal of Physical Chemistry A, 2018 Fluids confined in nanopores exhibit significant deviations in their structure and dynamics from the bulk behavior. Although phase, structural, and diffusive behaviors of confined fluids have been investigated and reported extensively, confinement effects on the vibrational properties are less understood.

Study on the Influence of Bottom Hole Confining Pressure on High-Pressure Jetting Techniques
Shiyou jixie, 2021 As the development of oil and gas resources continues to deepen, the impact of bottom hole confining pressure on high-pressure water jetting has become more and more prominent. To compare the rock-breaking performance of high-pressure water jet under the

Effects of confining pressure, pore pressure and temperature on absolute permeability. SUPRI TR-27 [PDF]
, 1981 This study investigates absolute permeability of consolidated sandstone and unconsolidated sand cores to distilled water as a function of the confining pressure on the core, the pore pressure of the flowing fluid and the temperature of the system.
