Explosive volcanic eruption requires that magma fragments into discrete parcels. Silicic magma can fragment through brittle failure or other processes that depend on the viscoelasticity of the melt. Owing to the low viscosity of basaltic magmas, however, the fragmentation mechanism must be different and will be governed by fluid mechanics alone. We perform a series of decompression experiments ...

BACKGROUND AND OBJECTIVES Limited information exists regarding the induction of explosive vapor and cavitation bubbles in an endodontic rinsing solution. It is also not clear whether a fiber has to be moved in the irrigation solution or can be kept stationary. No information is available on safe power settings for the use of cavitation in the root canal. This study investigates the fluid moveme...

Explosive extrusion of cold material from the interior of icy bodies, or cryovolcanism, has been observed on Enceladus and, perhaps, Europa, Triton, and Ceres. It may explain the observed evidence for a young surface on Charon (Pluto’s surface is masked by frosts). Here, we evaluate prerequisites for cryovolcanism on dwarf planet-class Kuiper belt objects (KBOs). We first review the likely spat...

Recently, in the field of CG, the animation of flame or smoke which uses the fluid simulation is researched. In this paper, we researched the particle-based visual simulation of plume fluid. Plume is fluid with a mushroom-like shape. For example, it is explosive flame or cumulus. Plume, such as continuously growing flame or cloud with an expansive gush, is a difficult phenomenon to represent wi...

The purpose of this paper is to provide a numerical modeling of intense dynamic loads on engineering materials. Numerical results illustrate the evolution of the state of elastic-plastic shells (filled with fluid or elastic-plastic material), which are subjected to explosive loads.

This work presents a Direct Ghost Fluid Method (DGFM) as part of two-fluid numerical framework suitable to model explosive gas and water flows resulting from underwater explosion (UNDEX). Due the presence with shock waves in modeling domain, classic Eulerian methods inherent diffusion may not be effective. Numerical occurs due nonphysical diffused density at material interfaces, which creates s...

Incidents relating to thermal fluid systems are unfortunately more common than we might realise, and can be extremely serious. The fire and explosion hazards with thermal fluid systems have been re-emphasised by recent incidents. These incidents have a direct bearing on the estimated 4,000 UK companies that operate thermal fluid systems. Water or steam can be used as heat transfer fluids, but w...

a novel mathematical model has been developed to aid the formulation of emulsion explosives. this mathematical model calculated heat of explosion, oxygen balance and raw material cost as a function of explosive ingredients, and the solution of the mathematical model was obtained by a ms excel program. the effects of the different content of nh4no3, nano3, h2o, and span-80 and composite fuel oil...
