[2]Department of Advanced Electromagnetics, Ilmenau University of Technology, Ilmenau, Germany
[3]Electrothermal Energy Conversion Group, Ilmenau University of Technology, Ilmenau, Germany

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

Deformation of Drop-within-Drop System under the Influence of High Intensity Oscillating Electric Field

D. Das[1], R.S. Patil[1], S. Kulkarni[1], V.A. Juvekar[1], and R. Bhattacharya[2]
[1]IIT Bombay, Mumbai, Maharashtra, India
[2]India Atomic Energy Regulatory Board, Mumbai, Maharashtra, India

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

Numerical Simulation: Field Scale Fluid Injection to a Porous Layer in Relevance to CO₂ Geological Storage

S. Kim[1], S. A. Hosseini[1], S. D. Hovorka[1]
[1]Bureau of Economic Geology, The University of Texas at Austin, Austin, TX, USA

CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... En savoir plus

Simulation Based Design of a Bladeless Centrifugal Flow Compressor

Ingo Schaarschmidt¹, Philipp Steinert¹, Andreas Schubert¹
¹Chemnitz University of Technology, Chemnitz, Saxony, Germany

The bladeless centripetal flow turbomachinery or disc turbine was invented by Nikola Tesla with the aim to realize a turbine with higher efficiency and simplicity compared to the state of the art at that time. Unlike conventional turbines, the disc turbine does not use rotor blades. ... En savoir plus

Comparison Between Phase Field and ALE Methods to Model the Keyhole Digging During Spot Laser Welding

V. Bruyere[1], C. Touvrey[1], P. Namy[2]
[1]CEA-DAM, Is-sur-Tille, France
[2]SIMTEC, Grenoble, France

Nowadays, spot laser welding is a full-fledged part of industrial manufacturing and is routinely used due to its advantages. It generates very located temperature gradients, and therefore, induces small distortions in the pieces. The COMSOL Multiphysics® software is used to model the ... En savoir plus
