0930703ClarkeThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Granted funds will support acquisition of a Planar Laser-Induced Fluorescence (PLIF) imaging system and shock wave tube to study the dynamics of simulated volcanic eruptions in laboratory experiments. Laser-based multi-phase fluid dynamic diagnostic capabilities will enable simulation of a range of particle laden nonsteady flows including subaerial volcanic eruptions and hydrothermal black smokers. PI Amanada Clarke and her students will focus on experimental simulation and quantitative observation of the fluid dynamics of Vulcanian eruptions, base surges, lateral blasts, and shock-generating explosions. Laboratory results will be compared with field observations and numerical eruption models in order to improve volcanic hazards predictions.

0930703Clarke 该奖项由 2009 年美国复苏和再投资法案（公法 111-5）资助。 拨款将支持购买平面激光诱导荧光（PLIF）成像系统和冲击波管，以研究实验室实验中模拟火山喷发的动力学。 基于激光的多相流体动力学诊断能力将能够模拟一系列充满颗粒的非稳定流，包括地面火山喷发和热液黑烟囱。 PI Amanada Clarke 和她的学生将专注于火山喷发、底部涌动、横向爆炸和冲击爆炸的流体动力学的实验模拟和定量观察。 实验室结果将与现场观测和数值喷发模型进行比较，以改进火山灾害预测。
