项目摘要
EAR-0447113Lange The goal of this project is the development of a high-pressure acoustic interferometer that can be used to measure the sound speed and density (and thus compressibility) of silicate liquids in an internally heated pressure vessel (IHPV). We plan to develop two different techniques at elevated pressure: (1) the frequency sweep method to measure liquid sound speed, and (2) the reflection coefficient method to measure liquid density. We will use an existing IHPV that is operable to 0.3 GPa and 1200 degrees celsius. Funds from this grant will be used for various equipment and machine shop costs and to partially support a full-time technician. Measurement of the density and compressibility of silicate liquids at high pressure is a major experimental imperative in the earth sciences, especially when applied to volatile-bearing melts. These data are needed for accurate thermodynamic calculations of crystal-melt and fluid-melt equilibrium at depth, which in turn are required for quantitative models of partial melting, melt transport, crystallization and degassing, and the mechanics of magma eruption. The graduate students involved in this project will obtain a strong background in thermodynamics, acoustics and signal processing, as well as petrology and geochemistry. It is anticipated that the techniques that we develop will become widely used throughout the ultrasonics and earth sciences community.
该项目的目标是开发一种高压声学干涉仪,可用于测量内部加热压力容器(IHPV)中硅酸盐液体的声速和密度(以及压缩性)。 我们计划发展两种不同的高压测量技术:(1)频率扫描法测量液体声速,(2)反射系数法测量液体密度。我们将使用现有的IHPV,可操作到0.3 GPa和1200摄氏度。 这笔赠款的资金将用于各种设备和机械车间的费用,并部分支持全职技术人员。硅酸盐液体在高压下的密度和可压缩性的测量是地球科学中的一项重要实验要求,特别是当应用于含挥发分的熔体时。 这些数据是需要精确的热力学计算的晶体熔体和流体熔体的平衡在深度,这反过来又需要定量模型的部分熔融,熔体输送,结晶和脱气,以及岩浆喷发的力学。 参与该项目的研究生将获得热力学,声学和信号处理以及岩石学和地球化学的强大背景。预计我们开发的技术将在整个超声波和地球科学界得到广泛应用。
