Over the last few years, Finite Element Models have become increasingly important as tool for the design of process control strategies or process optimization. Some processes possess complex spatio-temporal coupled and nonlinear dynamic. For process optimization it is very important to know the impact of parameters and state variables to the relevant process “output” parameters. In the glass ...

Simulation models for steady state thermal hydraulics analyses of ORNL’s HFIR have been developed using COMSOL. A single fuel plate and coolant channel of each type of HFIR fuel element was modeled in three dimensions. The standard k-? turbulence model was used in simulating turbulent flow with conjugate heat transfer. The COMSOL models were developed to be fully parameterized to allow ...

We have developed a numerical model to represent the effect of injection test in unsaturated porous and fractured rock mass. The test was conducted at the LSBB (Laboratoire Souterrain à Bas Bruit) site close to Rustrel, Vaucluse, France in the field of the French ANR project called “HPPP-CO2”. The results underline the impact of fractures on the hydro-mechanical response of the rock-mass. Indeed ...

This paper will describe the dependence of capacitive accelerometer characteristics on the accelerometers physical dimension and its material properties. The sense element of the accelerometer is designed on the basis of a commercially available torsion based accelerometer technology. The sense element consists of an asymmetrically shaped flat plate of metal supported above a substrate surface ...

This paper shows how a time-dependent and non-linear simulation of the dynamic operation behavior of an induction machine is executed by means of the \"Rotating Machinery\" interface from COMSOL Multiphysics 4.2a. The two-dimensional FEM model is connected to electrical circuits by coupling the physics \"Rotating Machinery\" and \"Electrical Circuit\" interfaces. These circuits include the ...

Surface Plasmon Polaritions (SPPs), as electromagnetic waves localized at the surface of a metal, enjoy the unique properties to confine energy into sub-wavelength scale, which is beneficial for future photonic integration. However, the severe absorption caused by the metal influences the propagation distance greatly. Actually, SPPs loss can be compensated by optical parametric amplification in ...

One of the major challenges in designing µTEGs is to minimize power loss due to internal resistance (r) of Thermoelectric (TE) materials. To solve this problem we have performed simulation analysis and calculated the internal resistance of eight different TE materials. The internal resistances of these TE materials were then compared to the power generated across the copper electrode as seen in ...

In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the relative location of nucleus with respect to the electrical field, we found that the observed cell rotation was ...

Ohmic heating is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This is particularly useful for very thick fluids, those that burn on to hot surfaces and those with high solids content which would cause difficulties for conventional heating techniques. Processing of animal by-products (ABP) faces all these ...

Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines . However, due to its low sensitivity the use of NQR is still limited. One way to increase the sensitivity is to improve the RF coil by means of a better RF ...
