Modeling Research Reactor Fuel Plate Hotspots with the Thin Layer and Thermal Contact Feature in the COMSOL Multiphysics® Software
One challenge with converting nuclear research reactors to low enrichment fuels is the thermal-fluid performance. Local areas of high temperature, known as hotspots, limit reactor performance and thus require accurate modeling. A simplified fuel plate model is eveloped to compare ... Read More
Effect of Proximity on the Thermal Rating of a Single Power Cable in Ventilated Tunnels
Power transmission through power cables installed in ventilated tunnels has been increasingly used worldwide and offers a complex thermal environment. These cables are placed on supports or fixed close to the tunnel walls. Established correlations currently in use have been deduced from ... Read More
Simulation and Validation of Pan Evaporation Rates Using COMSOL Multiphysics® Software
The four foot diameter class A evaporation pan is used by the scientific community as the standard for determining evaporation rates for a number of purposes. The COMSOL Multiphysics® software provides the necessary tools to adequately develop synthetic estimates of evaporation values ... Read More
A COMSOL Multiphysics® Software Interface with GEMS3K for Modeling Reactive Transport (Geo)Chemical Processes
This paper presents a generic interface for reactive transport process modeling that was developed between the COMSOL Multiphysics® software Java API (transport model) and GEMS3K (reaction model). While the transport of different species, kinetics of dissolution/precipitation, system ... Read More
Simulation and Validation of Seasonal Soil Temperature Variations Using COMSOL Multiphysics® Software
The influence of the energy (heat) stored in the earth as a major factor in environmental soil processes is recognized by the soil science community. The heat (energy) supplied by the earth is known to fluctuate with depth below ground surface and time of year, obviously as a function ... Read More
Heat Transfer Simulation for Reliability Estimation of Additive Manufacturing Process using the COMSOL Multiphysics® Software
Selective laser melting (SLM) is a popular additive manufacturing (AM) process that creates 3D metal parts by fusing fine metallic powder together. However, it remains difficult to certify AM part as its final quality can largely vary, depending on material and process variations. These ... Read More
On the Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption
This work examined in detail the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer information from experimental breakthrough data and the consequences that may arise when doing so based on using a 1-D axially ...

Thermo-mechanical Modeling of Pu-238 Production Target at HFIR
The production model in the COMSOL Multiphysics® software makes use of the most up-to-date PIE data, material property inputs, and modeling methodology. The fully coupled thermo-mechanical equations are solved over the entire domain, significantly increasing the degrees of freedom ... Read More
Glass Transition of ABS in 3D Printing
In a commercial 3D printer head, plastic ribbon passes through a hot nozzle of an extruder to dispense liquid plastic droplets to construct the model. In this paper a 2D axisymmetric model of a 3D head is considered to study the secondary transition change from below the glass ... Read More
A Virtual Laboratory for the 4 Bed Molecular Sieve of the Carbon Dioxide Removal Assembly
Introduction: Ongoing work to improve water and carbon dioxide separation systems to be used on crewed space vehicles combines sub-scale systems testing and multi-physics simulations. Thus, as part of NASA’s Advanced Exploration Systems (AES) program and the Life Support Systems ... Read More
