Concentrated gas flows

Carbon dioxide emissions are frequently found at volcanic sites (e.g., La Soufrière de Guadeloupe) and non-volcanic sites (e.g., Nepalese geothermal sites).

Our research, led by the team Physics of Natural Sites (IPGP) as part of M.-M. Robert's thesis, aims at quantifying these emissions by simulating carbon dioxide flows at the surface near the sources.

Our approach includes numerical simulations, laboratory experiments and field measurements (Nepal, Azores, Antilles).

Stability of a lava dome

Lava domes are generally very unstable and difficult to observe in the field.

Our laboratory experiments allow us to study the influence of different parameters (e.g., eruptive flow, temperature) on the structure and stability of the lava dome under calibrated and controlled conditions.
