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 ...

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 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 ...

A model has been designed and constructed for the all-liquid, sodium borohydride/hydrogen peroxide fuel cell. The electrochemical behavior, momentum balance, and mass balance effects within the fuel cell are modeled using the Butler-Volmer equations, Darcy’s law, and Fick’s law, respectively within COMSOL Mutiphysics. The simulations performed with the model indicate that an optimal ...

The sodium borohydride and hydrogen peroxide liquid fuel cell developed at the University of Illinois shows promise as a viable energy source for a wide range of applications. To achieve higher powers for a fixed active area, an optimal flow field design is desired, and a coupled 2D-3D model of the fuel cell was developed using the COMSOL Multiphysics software package. The model is governed by ...

We present numerical simulations that complement our experimental results of the microwave heating of copper powder metal compacts in separate electric (E) and magnetic (H) fields of a TE102 cavity. In general, thermal dissipation in the compacts may be attributed to resistive heating, dielectric losses, and magnetic losses. These dissipative mechanisms are coupled to the fields by the effective ...

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 ...

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 ...
