中文摘要
9614376 Spera本研究将考察多相硅酸盐岩浆固液悬浮液和气液乳状液的流变性随剪切速率、温度和分散相体积分数的变化。具体的实验包括对钠长石熔体中气泡乳状液的粘度学测量,以及对体积百分比高达40%的固体与钙长石-透辉石二元熔体平衡的透辉石晶体人工悬浮液的粘度学测量。关于多相岩浆系统流动性质的权威实验研究仍然相当匮乏,从所提出的实验中获得的结果将使我们在理解这些材料的复杂流变性方面取得重大进展。如果我们想要了解岩浆系统的动力学和它们构成的自然灾害,这是至关重要的。
英文摘要
9614376 Spera This research will examine the rheology of multiphase silicate magmatic solid-liquid suspensions and gas-liquid emulsions as a function of shear rate, temperature, and disperse-phase volume fraction. Specific experiments include viscometric measurements of emulsions of air bubbles in molten albite at up to 40 volume percent vapor and of artificially-created suspensions of diopside crystals in equilibrium with anorthite-diopside binary melts at up to 40 volume percent solids. Authoritative experimental studies of the flow properties of multiphase magmatic systems remain quite scarce, and results obtained from the proposed experiments will lead to measurable progress in our comprehension of the complex rheological nature of these materials. This is essential if we are to understand the dynamics of magmatic systems and the natural hazards they pose.
