Offer Description
The PhD thesis work will take place at two sites: at FAST lab (Université Paris-Saclay and CNRS) in Orsay and at Laboratoire Magmas et Volcans (LMV, Université Clermont-Auvergne, IRD and CNRS) in Clermont-Ferrand. FAST is a research laboratory specialized in the hydrodynamics of complex flows linked to industrial processes, geophysical situations or biophysical processes. The PhD thesis work at FAST will be carried out within the "Granular and Suspension" team, which has extensive expertise in fluid mechanics and granular media. LMV is a research laboratory in the field of Earth Sciences. The PhD thesis work at LMV will be carried out within the Volcanology team, which has considerable expertise in the field of ground instabilities, pyroclastic flows and associated tsunamis.
The PhD thesis will be carried out as part of the CNRS TEGRAV project led by FAST and LMV, and will also be part of the ANR Slide2Wave project also led by FAST with LMV, Institut ∂'Alembert (Paris) and Institut de Mécanique des Fluides de Toulouse as partners.
Although many tsunamis are generated by earthquakes, some tsunamis are generated by subaerial gravity flows, which can occur not only in oceans, but also in lakes or rivers. Understanding such tsunami generation is a major challenge for environmental fluid mechanics, as the mechanisms at work in the generation of these waves are highly complex, with three interacting phases: solid grains, interstitial gas and water. The FAST (Orsay) and LMV (Clermont-Ferrand) laboratories wish to pool their well-established expertise in this field to conduct a joint experimental and systematic study of the mechanisms leading to the generation of tsunami-type waves by low-density gravity flows, with two complementary devices: one based on the direct collapse of an initial column of grains into water, and the other based on the fluidization of a granular flow along a slope before impacting the water. Modelling and numerical simulations will complement the experimental work.
