We present here our work on deconvolution of a magnetic probe to mesure electromagnetic emissions in near-field zone. To achieve this work,we have chosen a rectangular waveguide (WR90) as a radiating structure.Theoritical near-field is simulated using a FEM software (COMSOL) and also obtained by using a program based on transverse operator method (TOM), that lead to a very good field ...

We present a software tool for simulations of subsurface flow and solute transport in combination with comprehensive intra-phase and inter-phase geochemistry. The software uses PHREEQC as a reaction engine to COMSOL Multiphysics®. The coupling with PHREEQC gives major advantages over COMSOL’s built-in reaction capabilities, i.e., the soil solution is speciated from its element composition ...

In this paper , lab on chip (LoC) is proposed to detect an E.coli bacteria in water. LoC is a chip of size ranges from millimeter to few centimeter in which we can combine laboratory functions. The main components in lab on chip are micro fluidic structure, functionalized sensing block , measurements (interface)system. The microfluidic structure and sensing block is to be simulated in COMSOL ...

A Computational Fluid Dynamics study has been performed for a Gas Electron Multiplier (GEM) detector of high energy charged particles, currently under development as part of a new tracker of the high luminosity spectrometers in Hall A at Jefferson Lab. By gradual modifications of the geometry simulated in COMSOL, the design of the frame separating two GEM foils has been optimized with the aim ...

Rapid mixing is of essential importance in many microfluidic applications such as chemical reactions, drug delivery, sequencing or synthesis of nucleic acids, protein crystallization, etc. However, it is difficult to mix fluids in microchannels since flows in these channels are generally laminar and molecular diffusion is usually insufficient to mix fluids. Using a combination of turns and ...

The traveling wave ultrasonic vibration disks for dispersion of particles were designed by using of FEM analysis. The vibration disks are required specific vibration pattern, which contains three nodal lines. The vibration disk thickness was calculated to be matched the resonance frequency of bolted langevin type transducer and the specific vibration pattern. The alignment of the transducer was ...

COMSOL Multiphysics has been used to validate and check the design of a header transporting ammonia gases released from pressure safety valves (PSVs) to the tip of the flare. The header is part of a dedicated flaring system to contain emissions from ammonia storage tanks. The two main challenges are the low relief pressure and high capacity of the system. Another difficulty is the high relief ...

The safety assessment of the deep geological repository for nuclear waste of Olkiluoto (Finland) requires the evaluation of the influence of the land uplift (ice withdrawal) in groundwater. With this objective in mind, we have developed a three dimensional reactive transport model of the Olkiluoto, simulating the most relevant deformation zones in a three-dimensional domain. The evolution in ...
