Fragmentation in thermal explosions
TLDR
In this article, a series of experiments involving explosions between molten tin and water is described, together with information from other work, indicate that thermal explosions usually involve several distinct interactions in the same mass of material, and that each interaction forms a bubble containing some vapour whose collapse initiates the next interaction.About:

Mechanisms of hydrovolcanic pyroclast formation: Grain-size, scanning electron microscopy, and experimental studies
TL;DR: In this paper, the authors analyzed over 200 samples of hydrovolcanic ash and determined five pyroclast shape types: blocky and equant, vesicular and irregular with smooth surfaces, moss-like and convoluted, spherical or drop-like, and plate-like.
Journal ArticleDOI
Hydrovolcanism: Basic considerations and review
TL;DR: In this paper, it was shown that the optimal mass mixing ratio of water to basaltic melt for efficient conversion of thermal energy into mechanical energy is in the range of 0.1 to 0.3.
Journal ArticleDOI
Vapor explosions in light water reactors: A review of theory and modeling
TL;DR: A comprehensive review of vapor explosion theory and modeling can be found in this paper, where the effect of scale on the mixing process coupled with the explosion propagation and efficiency is discussed. But, as discussed in this paper, some specific fundamental issues are either not well understood or require experimental verification of theoretical hypotheses.
Journal ArticleDOI
Littoral hydrovolcanic explosions: a case study of lava–seawater interaction at Kilauea Volcano
TL;DR: In this paper, a variety of hydrovolcanic explosions may occur as basaltic lava flows into the ocean and are most often initiated by collapse of a developing lava delta.
Journal ArticleDOI
Generation of fine hydromagmatic ash by growth and disintegration of glassy rinds
TL;DR: In this article, the authors consider a process of hydromagmatic ash formation that involves repeated growth and disintegration of glassy rinds on pyroclast surfaces as they deform within turbulent flows.

Collapse of an initially spherical vapour cavity in the neighbourhood of a solid boundary
TL;DR: In this paper, a numerical method was proposed to solve the problem of balloon bubble collapse near a plane solid wall, using finite time steps and an iterative technique for applying the boundary conditions at infinity directly to the liquid at a finite distance from the free surface.
Journal ArticleDOI
Critical speeds and sizes of liquid globules
TL;DR: In this article, it was shown that the critical value of Weber's number for falling drops is different from the one for drops suddenly exposed to a constant air flow, which latter case occurs, for instance, during disintegration processes of liquid jets.
Journal ArticleDOI
Explosions from molten materials and water
TL;DR: In this article, the authors used an explosion that took place in a foundry as an example, and explained the phenomenon as a mechanical reaction, which is known as a mechnical reaction or a chemical reaction.
Journal ArticleDOI
An experimental study of energy transfer processes relevant to thermal explosions
TL;DR: In this paper, the transient heating of a metal foil under water has been studied and both unstable and stable energy transfer processes have been shown to occur at temperatures above the nucleate boiling region and relevant quantitative heat flux data have been obtained.
