The Fluid Dynamics of Lava Flows: Silicic Domes and Basaltic Channels.

熔岩流的流体动力学：硅质穹隆和玄武岩通道。熔岩在地球、月球和类地行星的大部分表面流动。这一跨学科计划将结合实验室实验、数学分析、数值模拟和现场观测来阐明熔岩流动的复杂动力学，包括流动与表面凝固和底部熔融的非线性耦合。重点将放在熔岩穹顶的不稳定性以及明渠和管道中的流动上。预期结果包括：预测熔岩流动冷却和推进速率的能力、危险熔岩穹顶坍塌的指标、改进的火山灾害评估、对世界级岩浆矿床成因的解释以及对行星表面形态的新解释。

The Fluid Dynamics of Lava Flows: Silicic Domes and Basaltic Channels. Lava flows surface much of the Earth, Moon and terrestrial planets. This interdisciplinary program will combine laboratory experiments, mathematical analysis, numerical modelling and field observations to elucidate the complex dynamics of lava flows, including the nonlinear coupling of flow with surface solidification and basal melting. The focus will be on lava dome instability, and flow in open channels and tubes. Expected outcomes include: the ability to predict rates of lava flow cooling and advance, indicators of hazardous lava dome collapse, improved volcanic hazard assessments, explanations of the genesis of world-class magmatic ore deposits, and new interpretations of planetary surface morphologies.
