Geothermal energy systems require precise sizing to ensure efficiency and sustainability, particularly for probe fields and groundwater doublets. We present two specialized applications developed using COMSOL Multiphysics’ Application Builder, leveraging the Heat Transfer and Groundwater ... En savoir plus

Acoustical well logging is an important technology for petroleum industry. Calibration and testing of tools in real wells is not feasible because the cost is high and the condition is not controllable. During manufacturing and maintaining, the logging tools are usually tested in a fluid ... En savoir plus

Used for welding, cutting, deposition by projection, for the treatement of waste, or in analysis for ICP torches, for the synthesis of high purity silica or for the manufacture of nanometric powders or nanoparticules, thermal plasmas are fundamental in processing of materials and in ...

The presented paper describes a method for micro precision assembly of very small objects like future microchips, which have a lateral expansion equal to or smaller than 500 μm. The modelling and simulation of a fluidicbased micro assembly method for a microchip with a dimension of ... En savoir plus

Pore-scale modeling of multiphase flow through porous media is addressed most frequently to improve our understanding of flow and transport phenomena in such settings. It can be used to obtain macro-scale constitutive equations, to assign multiphase flow properties in large scale models, ... En savoir plus

FT wind sensors measure wind speed and direction using an acoustic field superimposed on a flow field in an acoustic resonator equipped with three piezoelectric transducers. The study proposed here focuses on the acoustic resonance technology of a simplified wind sensor geometry, and how ... En savoir plus

During the evolution of multicellularity, cells needed to find a way to self-organise into structures able to fulfil a broad range of physiological functions. Directed cell migration (DCM) is an elegant way to reorder cells and break symmetry based on simple rules and local information, ... En savoir plus

Conclusions about the influence of paper insulation on the electrical discharge initiation in mineral oil may be drawn on the basis of experimental studies. However, in some cases, these conclusions may be supported by electrical field analysis. Determination of maximum values of ... En savoir plus

Reducing greenhouse gas emissions and finding new ecological and renewable energy sources are among the biggest challenges humanity is facing nowadays [1] [2]. At the same time, power requirements are increasing constantly, where primary energy consumption is intrinsically accompanied by ... En savoir plus
