Zoback and Gorelick [(2012) Proc Natl Acad Sci USA 109(26):10164-10168] have claimed that geologic carbon storage in deep saline formations is very likely to trigger large induced seismicity, which may damage the caprock and ruin the objective of keeping CO2 stored deep underground. We argue that felt induced earthquakes due to geologic CO2 storage are unlikely because (i) sedimentary formation...

A hydraulic energy redirection and release technology has been developed for mitigating the effects of blast shock waves on protected objects. The technology employs a liquid-filled plastic tubing as a blast overpressure transformer to transfer kinetic energy of blast shock waves into hydraulic energy in the plastic tubings. The hydraulic energy is redirected through the plastic tubings to the ...

The (unconfined) vapour cloud explosion (VCE) is a dramatic phenomenon that generates severe pressure wave with high potential to damage assets and produce injuries in the far field. This definition applies also hydrogen. Nevertheless, no clear tools methodology have been so developed tested for this highly reactive gas, even advanced numerical simulations lack validation suffer from large unce...

In this study, under the open-close conditions of a roadway outlet, ANSYS/LS-DYNA was used to build models explosions on roadways with 0° and 90° bending angles, compare analyze shock wave propagation characteristics variation laws. Combined damage degree classification overpressure human body, destructive effect zoning explosion in condition opening closing entrance studied. The results showed...

Recent explosions with devastating consequences have re-emphasized the relevance of fire safety and explosion research. From earlier works, severity has been said to depend on various factors such as ignition location, type a combustible mixture, enclosure configuration, equivalence ratio. Explosion venting proposed measure in curbing impact, design vent requires deep understanding phenomenon. ...

This work is concerned with the consequence analysis of vapour cloud explosion (VCE) due to accidental release of hydrogen (H2) from the hydrogen holder in a chloralkali plant. Hydrogen is highly flammable if released accidentally may lead to flash fire or VCE which has the potential to damage people, equipment and facilities in the vicinity of the hydrogen holder. The equivalent TNT, TNO multi...

A Hydro-Geomechanical View of Seal Formation and Failure in Overpressured Basins — The formation of seals, and the consequent retention of overpressure, is a common and expected event during normal basin evolution in active basins that have a significant mudrock succession. Seal failure, and the resultant limitation to fluid-pressure increase (valve action), is also an expected process. Hydroge...

The ear is the organ that is most sensitive to blast overpressure, and ear damage is most frequently seen after blast exposure. Blast overpressure to the ear results in sensorineural hearing loss, which is untreatable and is often associated with a decline in the quality of life. In this study, we used a rat model to demonstrate the pathophysiological and structural changes in the inner ear tha...
