This research program represents a continuation of the collaborative effort between F.J. Spera and D. A. Yuen in studying the dynamical evolution and physical properties of crustal magma bodies by means of state-of-the-art numerical techniques on supercomputers. It will focus on two themes: (1) To continue the study of double-diffusive convection, which represents a unique feature of magma chamber fluid dynamics. (2) To initiate a new computational program in the determination of nonequilibrium transport properties of silicate melts from molecular dynamics. The goal is to obtain some basic understanding of the effects of pressure and shear-rate on the viscosity and diffusion coefficients of magmatic substances. These research areas will contribute to our understanding of the physics of melts and the dynamics of magma transport.

本研究项目代表了F.J. Spera和d.a. Yuen利用最先进的超级计算机数值技术研究地壳岩浆体的动力学演化和物理性质的合作努力的延续。重点研究两个主题：(1)继续开展双扩散对流的研究，这是岩浆房流体动力学的一个独特特征。(2)建立了从分子动力学角度确定硅酸盐熔体非平衡输运性质的新计算程序。目的是对压力和剪切速率对岩浆物质粘度和扩散系数的影响有一些基本的了解。这些研究领域将有助于我们对熔体物理和岩浆运移动力学的理解。
