New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...

The most successful nanofiltration models are those based on the combination of the Extended Nernst-Planck equation with the Donnan steric equilibrium. These models have been typically solved by using iterative procedures based on the Runge-Kutta method. Yet, such procedures present convergence problems in some cases. In this paper, we present an implementation of the original Donnan ...

The steady-state non-equilibrium distributions of two species of mono-valent ions around a charged nanofluidic channel have been examined. Large reservoirs were placed on either side of the nanoscale channel to simulate bulk concentration of ions in a fluid. Results from COMSOL Multiphysics simulations show that the effect of the potential bias across the nanochannel yields a significant ...

The performance of simplified cylindrical cloaks with various material parameters was investigated. The performance metric was the overall scattering width of the cloak with various objects in the hidden region. COMSOL was used to simulate three cloaks with different material parameters to determine the total field in the simulation domain. For all cloaks simulated in this effort, a PEC-lined ...

Due to the complexity of electromagnetic modeling, researchers and scientists always look for development of accurate and fast methods to extract the parameters of electronic interconnects and package structures. In this paper, we illustrate modeling of multiconductor interconnects in multilayered dielectric media using COMSOL Multiphysics and the finite element method. We specifically determine ...

The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper concerns the violins family: the geometry and the vibratory propagation of this instrument is very complicated to ...

COMSOL Multiphysics is a very helpful simulation software in our researches on both PEMFC and nanometer-sized electrodes. In the first part of our presentation, the influence of humidity and temperature to the performance of PEMFC are studied by simulating the MEA (membrane electrode assembly) in PEMFC. In the second part, models of different nanometer-sized electrodes, including spherical ...

The objective of the paper is the assessment of the wind load applied to a real photovoltaic (PV) platform installed on a site situated in Brasov, which belongs to the Transilvania University. The platform has a double-tracking axis mechanism which allows the rotation of the platform disk depending on the sun position, in order to gather the maximum solar yield to produce electricity. The study ...

Simulation tools for building physics problems play an important role in design and understanding the behavior of energy efficient buildings. There are different tools available for simulation of these problems, but each simulation tool has its own advantages and limitations. In this paper, a heat transfer problem in an exterior building wall with high performance materials has been simulated in ...
