Using COMSOL Multiphysics® software, a new model was implemented with the Physics Builder functionality, which provides a thermomechanical coupling. It consists of two independent physics interfaces, one for the mechanical, viscoelastic behavior and one for the heat transfer. With the multiphysics coupling features it is now possible to add the effects of thermal expansion and dissipation or ...

The kinetic interface-sensitive tracers (KIS tracers) are used to give a partial picture of the spreading, mixing and plume migration of supercritical carbon dioxide (scCO2) in the deep saline aquifer by estimating the interfacial areas between scCO2 and brine during the injection of scCO2. To get a better understanding of the KIS tracer reaction and transport processes in the two-phase flow ...

Transdermal drug delivery (TDD) is used to deliver drugs through the skin as an alternative to oral, intravascular, and subcutaneous routes. While there are many advantages to TDD, skin is a very effective barrier and provides resistance to drug delivery. To improve drug delivery through the skin, permeation enhancers are used. We developed an axisymmetric COMSOL Multiphysics® software model ...
Relativistic Quantum Mechanics Applications Using the Time Independent Dirac Equation in COMSOL Multiphysics® Software

 Consultant, East Lyme, CT, USA
The paper illustrates the use of the COMSOL Multiphysics® software (via the “Coefficient-Form PDE” option) for obtaining the relativistic quantum mechanics wave function ψm(x,y,ω), m=1,4 as a solution to the time independent Dirac equations. Once having ψm(x,y,ω), it can be used to compute the probability density ρ′=Σ|ψm|^2 of a particle being at a specific point within the spatial field under ...

Steam Generator Test Facility (SGTF) is set up in IGCAR to optimize the design of Steam Generators (SG) for Fast Breeder Reactors. In the SG of SGTF heat exchange takes place from sodium which enters at 525 ºC and leaves at 355 ºC temperature to the water/steam which enters at 235 ºC and leaves at 493 ºC. To reduce the steady state differential temperature and thermal shock during transients, ...

In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on the MNE-tips leads to a situation comparable to the whole-cell mode in classical Patch Clamp. MNE-penetration ...

A solidification process of casting explosives in shell is studied in this paper. An enthalpy method approach is used to model the solidification process. Both the thermal and mechanical effects are taken into account. An ALE (Arbitrary Lagrangian-Eulerian) method is used to represent the physical deformation due to solidification. Results from the model are verified against experimental ...

A small batch stirred cell which is operated at temperatures up to 400 °C and pressures up to 30 bar is used to study fouling behaviors of selected crude oils. COMSOL Multiphysics package is used for the CFD (Computational Fluid Dynamics) and heat transfer modeling for this stirred cell system. The simulation results are validated against the measured temperature data at various axial ...

The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by a finite-element simulation method, developed through the software package COMSOL Multiphysics 3.4.
