Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based fluid transport equations for various phases; near-equilibrium equation governing phase change from liquid ...

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 ...

An electromagnetic horn is a device used in particle physics to produce a strong pulsed toroidal magnetic field and to focus charged particles toward a detector. A multiphysics analysis is performed to assess the stress level inside the horn structure. In steady state regime, the horn is submitted to a thermal static stress due to thermal dilatation. Then, every 80 ms a strong magnetic field ...

Like humans, horses can develop a variety of dental problems. Different equine diseases occur in different areas of the equine cheek tooth or its surrounding tissues. With a realistic simulation of a chewing cycle it can be possible to link mechanical phenomena such as high stress in distinct areas to commonly occurring diseases. According to different angles of the acting chewing force, ...

We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental evaluations of the detection principle and are in the stage of optimization of several parts of the system. As ...

Silicon electrodes are presently being pursued as the potential negative electrode for lithium-ion batteries owing to its high gravimetric (mAh/g) and volumetric capacity (mAh/L) compared to the existing state of the art graphite electrode. Recent experimental studies have demonstrated the use of nano size Si electrodes which minimizes insertion induced stresses due to facile strain ...

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 ...

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 ...
