TL;DR: In this paper, the authors developed new correlations developed through numerical simulations to estimate peak overpressures for vented methane-air explosions in cylindrical enclosures, and compared to CFD simulations, the VMEOC correlations provided a faster way to estimate the peak overpressure of a vented explosion.

27 Jun 2013TL;DR: In this paper, a wind-tunnel investigation was conducted to determine the effect of wing planform on sonic boom at Mach numbers of 1.7, 2.0, and 2.7.
Abstract: A wind-tunnel investigation was conducted to determine the effect of wing planform on sonic boom at Mach numbers of 1.7, 2.0, and 2.7. The results of the investigation show that the wing leading-edge sweep is one of the primary planform variables affecting the overpressure characteristics.

TL;DR: It was found that blast wave propagates preserving supersonic speed along the tunnel accompanied by high overpressure levels, and indicating that space confinement favors the formation and maintenance of a shock rather than a weak pressure wave.

TL;DR: In this article, the authors show that the formation of conical sand intrusions may be favored by the pore-pressure gradients prevailing in the host rock before sand injection, and they make use of a Particle Imaging Velocimetiy (P.I.V) technique to analyse plastic deformation, showing that these inclined fractures are opened in mixed modes.
