Rheological controls on the dynamics of channeled lava flows

Robertson, Jesse Craig

Description

The influence of a viscoplastic lava rheology on the dynamics of channeled lava flows is analysed using numerical methods and analogue experiments. A numerical solution for the flow of a Bingham fluid in a rectangular channel is found using a multigrid-based augmented Lagrangian scheme. The numerical results show that an internal viscoplastic rheology significantly modifies the velocity distribution within a lava flow through the development of plug regions whose size is determined by the...[Show more]
