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

Large underground mines (LUMs), which constitute over 60% of metal and nonmetal mining operations in the United States, are critical to national infrastructure and materials supply (Bhattacharyya et al., 2023; Gendrue et al., 2021). These mines are characterized by vast entries exceeding ... 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

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 ...

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

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

A novel type of tunable surface acoustic waves (SAW) filter based on 1D phononic crystal controlled by electric is field proposed. The tunability of proposed filter varied over a wide range: 1-20%. Basic idea is electrical controlled induced periodical domains in ferroelectric film based ... En savoir plus

Lorentz Force Velocimetry (LFV) is a non-contact measurement technique used to determine flow rates in electrically conducting fluids by exposing the flow to an external magnetic field and measuring the Lorentz force acting on the magnet system. Typically, for LFV applications real and ... En savoir plus

This paper deals with the simulation study using COMSOL on the deformation of drop-within-drop system in a high intensity oscillating electric field. It consists of a composite drop suspended in a continuous phase. This composite drop has a smaller inner drop suspended within the larger ... En savoir plus
