Investigation of Transport Phenomena in Nanochannels and its Applications in Energy Conversion using COMSOL Multiphysics
Green Energy and Environment Research Laboratories, Industrial Technology Research Institute, Chutung, Hsinchu, Taiwan
Well‐designed and controlled nanochannels are ideal physical modeling systems to study fluidics in a precise manner. Electrokinetics refers to transport phenomena related to the non‐electroneutral EDL, which is created to neutralize the surface charges produced on surface. Surface charges are produced by the dissociation of surface functional groups. We created a mathematical model of a ...
Modeling Charge/Discharge Heat Generation of Li-ion Cells and Experimental Verification of Temperature Distribution
 Kobelco Research Institute, Inc., Kobe, Hyogo, Japan
Modeling the heat generation and the heat transfer of the electrode of lithium-ion battery are introduced. There are several models, such as an homogeneous heating model and a model considering the current and reaction distribution of electrode. Generally, electrodes have large area and the calculation load of the model becomes high. Therefore, some approximated models are required to analyze ...

Even though sonochemical reactors have been studied extensively for decades, there is limited data on their characterization when the volume of the sample is fixed. The Acoustics Module and COMSOL Multiphysics® software are used to resolve the pressure field. The validated numerical model will be used to compare different configurations; changing the Height (H), diameter (D) of the reactor and ...

The numerical study of temperature and acceleration sensitivities of a dual cavity Fabry-Perot (FP) interferometer is carried out using finite element method. The optical cavities are formed by machining two side-by-side circular bore of 12 mm each on a monolithic block of low expansion material. One cavity will be used to generate broadband channel spectra for accurate wavelength calibration of ...
Computational Multiphysics to Optimize Humidification Chamber for a Novel PEM Fuel Cell Power System Used in Automobile Application - new
Tata Motors, Bengaluru, Karnataka, India
Proton Exchange Membrane (PEM) fuel cells are quickly becoming an attractive technology due to their ability to meet increasing energy demands in a cleaner, more efficient way compared to existing methods. A fuel cell is an electrochemical device which converts the chemical energy of a fuel and an oxidant directly into electricity without the intermediate step of classical, chemical combustion ...

ICP phenomenon has been widely used for fabricating microfluidic devices of pre-concentration, micromixing and desalination. However, theoretical research and simulation of ICP have not been carefully dealt with. We provide a multiphysics simulation of a DC-ICP device based on improved numerical settings in this work.
