Simulated Thermal Response Test data are analyzed in order to evaluate the effect of the tridimensionality model’s feature in determining the proper value of the soil thermal conductivity and borehole thermal resistance, necessary for the geothermal energy storage systems’ design in real conditions. The 3D system’s simulation during the Thermal Response Test is realized by adopting the finite e...

Industrial processes assisted by highpower ultrasound have become an attractive field for industries because of its sustainability (low energy consumption, non-pollutant processes) and efficiency. Among these processes we can find food dehydration aided by ultrasound, based on the proper exploitation of the non-linear effects associated to finite-amplitude-wave propagation that are able to enha...

A set of microstructures for in situ stress measurement is presented, based on a lancet principle having dedicated designs for the amplification of dimensional variation induced by internal stress of the materials. The presented technique has an advantage over the traditional rotating structures and wafer curvature measurements in terms of the simplified readout mechanism. The test structures a...

We simulate the effect of the chaining direction of ellipsoidal particles of polar molecule dominated electrorheological (PM-ER) fluids using commercially available COMSOL Multiphysics® software for the distribution of electric field and the total electrostatic energy. It is proved that adding ferroelectric materials to the channels parallel to the short axis would make the short axis parallel ...

This paper presents 2D and 3D modeling of hysteresis motor using high temperature superconducting element Yttrium Barium Copper Oxide (YBCO) in the rotor. These hysteresis motors aim to improve the performance in comparison with that of conventional hysteresis motors. Various performance parameters of high temperature superconducting hysteresis motor are computed from the proposed 2D and 3D mod...

In this paper, we focus on the problem of optimizing plasmonic structures. A plasmonassisted waveguide coupler is considered as a test problem, which leads to a five-dimensional optimization problem carried out by an evolution strategy (ES). The optimization results are verified by a comparative analysis between different solvers, i.e., the finite element package CONCEPTs and the multiple multi...

An electrical double layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy – Chapman and Stern Model) are numerically solved for a flat surface electrode in the 3D Electrostatics mode of Comsol Multiphysics 3.5a Software. The values of the electric pot...

Coupling fuel performance and neutronics can help improve the prediction accuracy of rod behavior, which is important for design evaluation. A multiphysics coupled system was developed with software COMSOL 3D Monte Carlo neutron transport code RMC. The analysis module built on top ability to simulate behavior in two-dimensional axisymmetric (2D-RZ) or three-dimensional (3D) mode. RMC innovative...

Radioactive waste disposal, as the final step of open nuclear fuel cycle, is an important process to protect humans and environment from harmful effects ionising radiation. Approaching construction geological repository, understanding predictability behavior engineered barrier material becomes more than ever.

We describe methods and results of simulations done for predicting behavior of particles in an aqueous solution under an applied AC electric field on electrodes of rectangular and triangular shapes. Here the two major effects which come into play are Dielectrophoresis and AC electroosmosis. Two simulations have been presented, one for rectangular and one for triangular shaped electrodes. Both t...
