Papers
Time integration and steady-state continuation for 2d lubrication equations
Philippe Beltrame,Uwe Thiele +1 more
TL;DR: In this article, a Cayley transform is employed to overcome numerical problems resulting from scale separation in space and time, and an adaptive time-step allows to study the dynamics close to hetero- or homoclinic connections.

The GEOFLOW-experiment on ISS (Part III): Bifurcation analysis
TL;DR: In this paper, the critical aspect ratio and Rayleigh number corresponding to the (l, l+1) mode interaction were computed in the GEOFLOW-experiment framework and the existence of heteroclinic cycles versus the Prandtl number.

On fractal nature of groundwater level fluctuations due to rainfall process
Maminirina Joelson,Maminirina Joelson,Jacques Golder,Jacques Golder,Philippe Beltrame,Philippe Beltrame,Marie-Christine Néel,Marie-Christine Néel,Liliana Di Pietro +8 more
TL;DR: In this article, the authors analyzed hourly resolution time series of groundwater level fluctuations after removing the seasonal cycle and found that fluctuations of groundwater levels have fractal scaling and a persistent behavior.
Deterministic particle transport in a ratchet flow.
TL;DR: This study focuses on a simplified deterministic model of small inertia particles within the Stokes flow framework that is called "ratchet flow" and shows that, for large drag, the particle drift is similar to phase slip in a synchronization problem.
GeoFlow : European Microgravity Experiments on Thermal Convection in Rotating Spherical Shells under Influence of Central Force Field
Th. von Larcher,B. Futterer,Christoph Egbers,Rainer Hollerbach,P Chossat,Philippe Beltrame,Laurette S. Tuckerman,Fred Feudel +7 more
- 30 Jul 2008
TL;DR: In this article, the status of the GeoFlow-Experiment on board the International Space Station (ISS) is reported and an overview of experiment hardware preparation status, including application of measurement techniques, 3D numerical flow simulations, experimental work and the way of experiment data analysis.
