Numerical modelling of estuaries and coastal seas
Researcher: Valentin Vallaeys
Supervisor(s): Eric Deleersnijder

The topic of the research is the numerical modelling of the river-to-sea continuum of major rivers (i.e. Congo River and Columbia River). The goal is to study the estuarine and coastal dynamics and their interactions with tides, river discharges and atmospheric/oceanic circulations. This thesis partly answers the following questions: What is the dynamics of the river-to-sea continuum ? How does the small scale influence the larger one (and vice-versa) ? Can Discontinuous Galerkin methods reduce the numerical dissipation in order to simulate sharp fronts of density and velocity fields ? This thesis is performed within the framework of the SLIM project (

Automatic hexahedral mesh generation for boundary layers
Researcher: Christos Georgiadis
Supervisor(s): Jean-François Remacle

The main objective of our work is to provide with a fast and reliable method for generating boundary layer meshes. We follow a strategy that uses direction fields and a frontal point insertion strategy. The input of our algorithm is an initial triangular mesh of our domain and a direction field calculated on it. The goal is to compute the vertices of the final mesh by an advancing front strategy along the direction field. The final mesh will consists of right angle triangles, optimal for merging into quadrilaterals.

Tidal response of Titan liquid bodies
Researcher: David Vincent
Supervisor(s): Eric Deleersnijder

Titan, a moon of Saturn, has various liquid bodies: surface lakes and seas filled with liquid hydrocarbons and a global subsurface ocean of water.
I numerically studied the tidal flow (see Fig. 1, the tidal ellipses of the first tidal component in Kraken and Ligeia Maria) and motion of the surface lakes and seas by means of SLIM ( The harmonics of the tidal motion (for instance, the tidal range and phase in Kraken and Ligeia Maria, see Fig. 2) and eigenmodes were also studied in order to assess the likelihood of resonance (local or global). Values predicted by the model such as the tidal range and flow of the surface lakes and seas are useful for designing some aspects of the future observation missions.
I am currently modeling the tidal response of Titan's global subsurface ocean by taking into account the solid-fluid interactions with Titan icy crust (see Fig. 3, the sea surface elevation of Titan's ocean with a free top boundary). The dissipation and resonance phenomena will then be studied. The originality of this work lies in the fact that the dynamic tides are taken into account.
