Tools are developed that mine the mesh and simulation data provided by the finite-element mesher and solver in COMSOL. The tools developed are used in two applications. In the first, a thermal system is decomposed and an equivalent circuit (EC) is developed for reduced order modeling. In the second application which arises in robotics, the COMSOL mesh is used to plan paths of the robot ...

The interface between microelectrodes and biological tissue is of great interest to researchers working on extracellular stimulation. In this paper, we outline a method used to model the complex double layer capacitance at the interface between the electrodes and the cortex. This model relies on the combined power of SPICE, MATLAB, and COMSOL Multiphysics. The goal of this model is to ...

Electromagnetic waves within the Teraherz frequency spectrum are common in medical techonolgy applications, such as imaging, spectroscopy and drug detection. In this presentation, we explain how Teraherz Radiation is used in different applications, how to produce Electromagnetic waves in the Teraherz frequency, and how to analyze them. Simulations in COMSOL Multiphysics are included as ...

The main focus of this paper is the modeling, simulation, and analysis of the CaBr2 hydrolysis reactor stage in the Calcium-Bromine thermochemical water splitting cycle for nuclear hydrogen production. One concept is to use a spray reactor of CaBr2 into steam. Given the large heat reservoir contained in a pool of liquid CaBr2 that allows bubbles to rise easily, using a bubble column for the ...

The micromixer is one of the important components of Lab-On-a-Chip, but where the molecular diffusion, which is often a slow process, limits the mixing efficiency of two or more streams due to the unique laminar flows in these micro scale devices. This paper studies a mixing concept based on a vibrating micro-plate in the microfluidic channels to achieve an efficient mixing ability. A ...

The dynamics of fuel cell coolant flow with charged nanoparticles were modeled using COMSOL Multiphysics. A computational fluid dynamics physicochemical model of the multi-phase coolant flow has been formulated. For nanoparticles in the fluid, electrokinetic force, hydrodynamic force, and buoyancy forces have been taken into account for the prediction of electrodeposition rate onto channel ...

In this study, we show that the specific DNA hybridization is diffusion limited; whereas the non-specific hybridization is reaction limited. By means of an electrical field, DNA is put in motion. It results in an overallenhancement of the kinetics and a better ratio of specific hybrids over total hybrids.

The equations that govern motion in oceans and estuaries form a system of nonlinear partial differential equations for velocity, temperature and salinity fields set in complex bathymetries. A hierarchy of intermediate qualitative models have been proposed to help investigators understand the impact of wind stress, Coriolis force, and viscosity. We will present an analysis of these models ...

The combustion of lean methane in a catalytic flow reversal reactor (CFRR) is studied using COMSOL Multiphysics and a 2D continuum model. This model is based on mole and energy balance equations for the solid (the inert and catalytic sections of the reactor) and the fluid phases. The results show the impact on the methane conversion and the maximum temperature in the reactor of key ...
