At first, increase in hydrostatic pressure was 9 accompanied by a simultaneous increase of both Vp ...

Particle size effect on pore structure characteristics of ...

According to pore connectivity, pores in coal are divided into open and closed pores (Chen et al., 2020), with the main type of closed pores being gas pores (Niu et al., 2017; Chen et al., 2018b). Hou et al. (2017) and Chen et al. (2018b) concluded that with decreasing particle size, the progressive increase in pore volume is attributed to the release of many closed pores in high rank coals ...

The use of ultrasonic cavitation for kidney stone crush

Large kidney stones can obstruct the urethra and cause severe pain or infection. Current non-invasive approach for kidney stone crush called extracorporeal shock wave lithotripsy has been employed since 1980.In ESWL, multiple shock waves with various pulse repetition frequency (PRF) are used to shatter the stones.

solid/fluid substitution scheme constrained by pore-scale ...

In order to account for the pressure dependency of the elastic moduli, Sun et al. proposed a triple-porosity model, in which the pore space is divided into stiff, intermediate and compliant pores.This triple-porosity structure is necessary for adequate characterization of the pore geometry, which in turn is essential for modelling the fluid effects (de Paula et al.2012; Sun et al.2018).

The paper addresses the use of laser ultrasonic structuroscopy to study how weathering affects the internal structure of rocks used for facing buildings. For 1,250 hours rock samples were subjected to 150 cycles of freezing (at-20°C) and thawing in water (at +20°C) to determine their frost resistance. Also, moistened every 30 minutes, rock samples were exposed to thermal and ultraviolet ...

Uniaxial Test - an overview | ScienceDirect Topics

In very porous limestones a critical pressure beyond which stress-strain behaviour becomes non-linear was observed, which corresponds to pore collapse and grain crushing (Vajdova et al., 2004). Elastic, inelastic, and failure properties of carbonate rocks can be related to their porosity, and carbonate compressibility increases with porosity.
