In collaboration with Tristan Biard (LOG UMR 8187) and Laget Manon (Doctorante – LOG UMR 8187) we propose an analysis of field measurements of deep sea particle sinking fluxes.
Internship main location : Laboratoire d’Océanologie et Géosciences (UMR 8187) – Wimereux – France
Internship description and application rules: M2_internship_proposal
Visualization of the velocity field in a moderately turbulent Kolmogorov flow (spatial resolution 128^3). The flow is sustained by a steady unidirectional force (here along the X axis) with a monochromatic sinusoidal dependence proportional to sin(k Y). The sinusoidal profile is clearly reflected in the large scale velocity field in the X-Y planes (visible at the beginning and at the end of the movie).
Particles and copepods 3D trajectory tracking in a turbulent experimental flow by means of particle image velocimetry (duration: 6 months, from feb-march 2022, for M2 students in the french system or equivalent level for candidates from abroad).
More info here (french only): [6 months internship]. Applications to be sent by email to F.G.Schmitt and myself.
How does the shape of ice depend on the lateral and vertical confinement in a convective cell? In which conditions can we get the maximal amount of ice? How many possible equilibrium states can we observe for this system? We have tried to rationalize these questions by means of simulations and experiments. Read about it in Equilibrium states of the ice-water front in a differentially heated rectangular cell, Ziqi Wang, Enrico Calzavarini and Chao Sun [ https://arxiv.org/abs/2108.13253 ] soon also on Europhys Lett.
