Full System Modeling and Validation of the Carbon Dioxide Removal Assembly

R. F. Coker[1], J. Knox[1]
[1]NASA Marshall Space Flight Center, Huntsville, AL, USA

The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics ... Read More

Delamination of Sub-Crustal Lithosphere

P. Vincent[1], E. Humphreys[2]
[1]College of Earth, Ocean, & Atmospheric Sciences, Oregon State University, Corvallis, OR, USA
[2]Department of Geological Sciences, University of Oregon, Eugene, OR, USA

Introduction: Lithospheric delamination beneath the western U.S. is believed to be the driving mechanism responsible for the evolution of magmatic and topographic features observed at the surface in the western U.S.. This process requires hot asthenosphere to be in contact with the ... Read More

CFD/Electromagnetics Interactions via Realistic Heat and Mass Transfer to Moist Substrates

G. Ruocco[1], M. V. De Bonis[2]
[1]Engineering College, University of Basilicata, Potenza, Italy
[2]Institute of Food Science and Production, National Research Council, Bari, Italy

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... Read More

Fluid Leakage Across a Pressure Seal

R. P. Ruby[1], G. Kulkarni[2], U. Kanade[1]
[1]Noumenon Multiphysics Pvt. Ltd., Pune, Maharashtra, India
[2]Oneirix Engineering Laboratories Pvt. Ltd., Pune, Maharashtra, India

Seals or gaskets that are compressed between walls of a container are important to many industrial applications. In this paper we present a fluid flow model for predicting the sealing performance of such seals. A computational study using COMSOL Multiphysics® software suggests very ... Read More

3D Multiphysics Analyses to Support Low Enriched Uranium (LEU) Conversion of HFIR

P. K. Jain[1], J. D. Freels[1]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA

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 ...

Simulation of Droplet Impingement on a Solid Surface by the Level Set Method

J. Hu[1], R. Jia[1], K. Wan[2], X. Xiong[3]
[1]Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA
[2]Mechanical and Industrial Engineering, Northeastern University, Boston, MA, USA
[3]Department of Electrical Engineering, University of Bridgeport, Bridgeport, CT, USA

The dynamic behavior of droplet impingement on a solid surface is important to many engineering applications. This paper studied the dynamic behavior of a droplet impinging onto solid dry surfaces with different surface wettability using the COMSOL Multiphysics® software. The simulation ... Read More

Biofluid-Structural Interaction in Abdominal Aortic Aneurysm for Predicting Timeline to Rupture: The Effect of Hypertension and Aorta Wall Material Properties

K. Cluff[1], H. Mehraein[1], G. Jayakumar[2]
[1]Bioengineering, Wichita State University, Wichita, KS, USA
[2]Industrial & Manufacturing Engineering, Wichita State University, Wichita, KS, USA

An abdominal aortic aneurysm (AAA) is a bulge formed in the large blood vessels that supply blood to the abdomen, pelvis, and legs. A fluid structure interaction model was developed in a 3D aortic aneurysm model, which was constructed from abdominal CT scan images. Combining medical ... Read More

Thermal Study of Valve Regulated Lead Acid Batteries and Electronics Chamber Used in Stand-Alone Street Lighting Applications

D. Groulx[1], J. Skaalum[1], T. Jamieson[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

This paper presents a study on the heat generation of Valve-Regulated Lead Acid (VRLA) batteries used in off-grid streetlighting applications from PoleCo, a Halifax based company. One goal of the project was to produce validated COMSOL® models of the enclosure that holds these VRLA ... Read More
