中文摘要
岩浆中的气泡能否将气体从液态岩浆中分离出来,这决定了喷发的方式。以前使用固体浮石/渣油的研究表明,稳定的渗透性流动会导致放气。在这项研究中,我进行了一个从液体泡沫中放出气体的模型实验,并表明这种稳定的渗透性流动不会发生。我还建立了一个方程来定量地解释液体泡沫的放气量。
英文摘要
Whether bubbles in magmas can segregate (outgas) from the liquid magma determines eruption styles. Previous studies using solid pumice/scoria have suggested that steady permeable flow causes outgassing. In this study, I perform a model experiment of outgassing from a liquid foam and show that such a steady permeable flow does not occur. I also formulate an equation to explain the outgassing volume from liquid foam quantitatively.
