PI将进行基础的实验室研究 具有重要地球物理意义的流体力学过程 应用. 他将进行一项实验室研究 几种几何中的Rayleigh-Taylor不稳定性类 与大洋中脊的火山活动有关。 这将检查 最近提出的分割模型的有效性观察 在大洋中脊 他还将调查一部小说- 岩浆流动的稳定性是由于 岩浆粘度随温度的变化 他将说明这一点 裂缝和熔岩的实验室模拟物的不稳定性 流量和量化的长度和时间尺度， 发展起来的

The PI will carry out laboratory studies of fundamental fluid mechanical processes which have important geophysical applications. He will carry out a laboratory study of the Rayleigh-Taylor class of instability in several geometries relevant to volcanism at mid-ocean ridges. This will examine the validity of recently proposed models of the segmentation observed at mid-ocean ridges. He will also investigate a novel in- stability of magma flow which is due to the strong variation of magma viscosity with temperature. He will illustrate this instability in laboratory analogues of both fissure and lava flows and quantify the length and time scales over which it develops.
