Offre de Post-Doc :Gravitationally-driven turbulent exchange flows in a closed tube in the presence of a linear viscosity stratification
General context :
The exchange of viscous fluids induced by a Rayleigh-Taylor instability (RTI) in a confined environment is encountered in a variety of geophysical and industrial problems. For instance, this type of flow is suspected to control the distribution of magma and gas (SO2) released in some types of volcanic eruptions (Stevenson & Blake 1998). Similarly, these exchange flows modify the pressure drop in secondary or enhanced hydrocarbon recovery processes (Joseph et al. 1997). They are also involved in some of the initial stages of the inertial confinement fusion process. The motivation of the proposed post-doctoral project lies in the latter context.
Candidate’s profile
The successful candidate holds a PhD in fluid mechanics. He/she is autonomous in conducting experiments, implementing optical methods and using advanced image processing techniques. He/she has a very good fundamental background in turbulence and mixing physics. Previous experience in the use of direct simulation codes would be a real plus.
