This paper presents some results of numerical simulations carried out to investigate the basic hydrodynamic interactions between the laminar flow in the water column above triangular bedforms and the Darcian flow in the underlying permeable sediments. The flow was described by the Navier ... En savoir plus
Understanding the stress-strain behavior of human foot tissues and pressure map distributions at the plantar interface is of interest into biomechanical investigations. In particular, monitoring plantar pressure maps is crucial to establishing the perceived human comfort of shoe insoles. ... En savoir plus
Tetrafluoroethylene (TFE) is a gas widely employed in industry, which can under specific circumstances experience an exothermic dimerization to octafluorocyclobutane. If the heat generated by this reaction cannot be dissipated to the surroundings, the temperature inside the reactor will ... En savoir plus
The electrical stimulation for retinal implant has known significant improvements in the last decades with many implantations and experimentations. The ability to create better controlled and adapted signals to increase the efficiency in stimulation is a major objective. The aim of this ... En savoir plus
The Transfer Matrix method in the Acoustics Module of COMSOL Multiphysics is used when the whole system can be represented into a sequence of subsystems that interact only with adjacent subsystems. This method is frequently used in mathematics and, particularly, in acoustics. The ... En savoir plus
In the frame of an ESA project, CSEM in collaboration with other partners has developed an innovative Attitude Orbit Control System concept that relies on a Reaction Sphere. We propose to use one unique magnetic bearing Reaction Sphere whose spin axis and angular velocity can be ... En savoir plus
Liquid metal loops are used for heat removal and for the study of certain magneto-fluidic phenomenon like MHD (Magneto-Hydro Dynamic) effects. These loops operate at high temperatures and carry fluids that are invariably toxic in nature. Ensuring the purity of fluid in a closed loop ... En savoir plus
A set of microstructures for in situ stress measurement is presented, based on a lancet principle having dedicated designs for the amplification of dimensional variation induced by internal stress of the materials. The presented technique has an advantage over the traditional rotating ... En savoir plus
Three-dimensional finite element (FE) modeling of magnetic flux leakage (MFL) technique has been performed using COMSOL 3.4 for prediction of leakage fields from surface and sub-surface defects in a 12 mm thick carbon steel plate. The tangential and normal components of leakage fields ... En savoir plus
Recently adsorptive storage has been identified as the most promising low-pressure (3.5 - 4.0 MPa) alternative for storing natural gas for vehicular use. However in order to successfully implement this technology, the filling and discharge characteristics of the adsorbent bed must be ... En savoir plus
