Failure of conventional lead-acid battery is attributed to degradation of solid active mass (PbO2 and PbSO4 ). A number of research efforts are underway worldwide to overcome degradation of active mass to improve the cycle life of lead-acid batteries. Soluble lead-acid flow battery (SLFB) is a new kind of lead-acid flow battery in which products of discharge remain in dissolved state. SLFB ...

Numerical simulation of oxygen tension was performed to develop a microfluidic device for three-dimensional real-time observation of cellular response under hypoxia. The optimal experimental condition was obtained through investigations of effects of parameters, such as device thickness and flow rates of media and gas, on oxygen tension.

COMSOL Multiphysics® has been used to develop assessment tools for the NASA-sponsored Precision Combustion, Inc. (PCI) regenerable Microlith®- based adsorber modules. The Full Scale Water Removal (FSWR) PCI Microlith® was initially modeled for comparison with exit velocity data, measured while exterior canister was removed. Measurement data as well as flow analysis showed that the velocity ...

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium (LEU) fuel are ongoing at Oak Ridge National Laboratory as part of an effort sponsored by the U.S. Department of Energy’s Global Threat Reduction Initiative Reduced Enrichment for Research and Test Reactors program. COMSOL Multiphysics® models are ...

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 ...

Vibration produced by offshore wind turbines during their normal operation transmits through the tower into the foundation where it interacts with the surrounding water and is released as noise. The noise produced by offshore wind turbines can be detected by fish and marine mammals and may lead to alteration of their behavior. Given that noise is emitted at the interface between the foundation ...

Our GeoPET camera is explicitly dedicated for and well capable of 4D monitoring of solute transport in dense geological material, c = c(x,y,z,t) [1-4]. We apply COMSOL Multiphysics® for reproducing our experiments and extracting parameter sets for our 4D problems [5-6]. By aligning simulated results of anisotropic diffusion in clay to our observations we are able to clearly differentiate and ...

Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible structures that combines the concepts of cilia (flexible elastic elements) and rectifiers (e.g., Tesla pump). We ...
The Organizing Committee of the Iberian COMSOL Multiphysics Conference 2014
