Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM). It is proven to be able to provide a computationally ... Mehr lesen
A series of 2-D finite element models of a ZrO2-ZrW2O8 composite system were created in COMSOL Multiphysics to study the effect of pores between the matrix (ZrO2) and filler (ZrW2O8) materials. Pores were modeled as ellipses concentric with the filler particles. Seventeen model ... Mehr lesen
High power Lower-Hybrid RF waves injected at in a Tokamak plasma can strongly modify the edge plasma. This is caused by ponderomotive forces pushing charged particles in an inhomogeneous oscillating electromagnetic field towards weaker field areas. On the Alcator C-Mod Tokamak, edge ... Mehr lesen
Recently, the concepts of fractal geometry have been introduced into electromagnetic and plasmonic metamaterials. With their self-similarity, structures based on fractal geometry should exhibit multi-band character with high Q factors due to the scaling law. However, there exist few ... Mehr lesen
Different configurations of MEMS based accelerometer has been made and analysed using COMSOL Multiphysics. The designs presented in this paper consist of a square shaped proof mass with flexures supporting it. Different position and varied number of supporting flexures attached to the ... Mehr lesen
Nanorobots may be used in the advancement of medical technology, healthcare, and environment monitoring by swimming in biological fluids flowing in narrow channels of a few hundred nanometers in the area of bio-medical engineering. The pronounced effects in nanometer scale such as ... Mehr lesen
In this study, magneto-rheological elastomer (MRE) composite beams made of Barium hexaferrite (BaM) and Iron (Fe) powders combined with a highly-compliant matrix material were simulated using COMSOL\'s Solid Mechanics and AC/DC modules. The goal of the work was to develop models capable ... Mehr lesen
Ferrimagnetic based, coaxial nonlinear transmission lines (NLTLs) provide a means to generate sub-nanosecond risetime pulses (from nano-second input pulses) or megawatt level high power microwave oscillations, depending on the geometry, material, and external bias fields. This ... Mehr lesen
The classical optimization method has been applied to many design problems for electromagnetic systems. One of its major difficulties is related to meshing problems arising from shape modifications. In order to circumvent these kinds of technical difficulties with moving mesh problems, ... Mehr lesen
In this paper, the cyclic voltammetry behavior of Ferrocyanide/Ferricyanide, which is commonly used for electrochemical DNA detection experiment, was studied in the commercial EQCM-D setup (Q-sense) using the COMSOL Multiphysics. The model was established in a 3D geometry of QCM liquid ... Mehr lesen
