The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with an equilibrium loading, desorption is then accomplished by reducing the pressure to near vacuum. This type of ...

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 ...

Solders are typically used to join similar or dissimilar metals, referred to as substrates. In some cases solders are also used to join completely different classes of materials. For example, a joint between copper busbar and silicon solar cell represents a set of dissimilar substrates. In the formation of a solder-substrate couple, the system must have been subjected to at least a single ...
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 ...

The Levant has been repeatedly devastated by numerous earthquakes since prehistorical times. In order to understand the role of the dynamics of the water bodies in triggering the deformations in the Levant basin, a new theoretical thermo-mechanical model is constructed and extended by including a fluid flow component, in COMSOL Multiphysics simulation environment. The latter is modeled on a ...
Large Ray Optics Simulations for the Prediction of Solar Radiation Concentration Due to Reflective Walls

Abstract: Some of recent and unconventional buildings are using reflective material for their walls. In case of curved walls, like in the Vdara Hotel tutorial, or of complex shape walls like in the present case, the risk of solar radiation concentration is difficult to predict. Such concentration may damage the impinged material. Then it has to be studied by simulation. The presented case ...
Research and Development of Multiphysics Models in Support of the Conversion of the High Flux Isotope Reactor to Low Enriched Uranium Fuel
The findings presented in this report are results of a five-year effort led by the Research Reactors Division (RRD) of the Oak Ridge National Laboratory (ORNL), which is focused on research and development toward the conversion of the High Flux Isotope Reactor (HFIR) fuel from high-enriched uranium (HEU) to low-enriched uranium (LEU). This report focuses on the tasks accomplished by the ...

Descemet membrane detachment (DMD) happen when the aqueous humour (AH) in the aqueous chamber flow into the descrement membrance (DM) space through a break and separate the membrane from the stroma. This often happen after the cataract surgery. The fluid is driven by the buoyancy force that generated by to the existing of temperature different between the cornea and the pupil. COMSOL ...
