Modeling the Effect of Headspace Steam on Microwave Heating of Mashed Potato

J. Chen[1], K. Pitchai[1], D. Jones[1], J. Subbiah[1]
[1]University of Nebraska-Lincoln, Lincoln, NE, USA

Introduction: Domestic microwave ovens are widely used to heat food products, because of rapid and convenient heating. Nonuniform heating is the biggest issue in microwave heating process, which also causes food quality and safety issues. Microwave heating models are promising tools to ... Read More

COMSOL Multiphysics® Simulation of 3D Single-Phase Transport in a Random Packed Bed of Spheres

A. Dixon[1]
[1]Department of Chemical Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

Packed beds are important in the chemical industries. Computational fluid dynamics (CFD) can simulate detailed flow and scalar transport in packed beds for improved understanding and quantitative information. We present simulations of single-phase gas flow, conjugate heat transfer and ... Read More

3D Modelling of Flow Dynamics in Packed Beds of Low Aspect Ratio

F. Alzahrani[1], F. Aiouache[1]
[1]Engineering Department, Lancaster University, Lancaster, UK

This work used the 3D CFD modeling to investigate non-uniform deactivation in packed bed reactors of low aspect ratios under steady state and dynamic operations. In order to explore the effects of condition of instability on local deactivation, detailed knowledge of flow dynamics (i.e. ... Read More

CFD Simulation of Internal Flow Field of Dual-mode Scramjet

C. Butcher[1], K. Yu[1]
[1]University of Maryland, College Park, MD, USA

The complex internal flow field of a hypersonic air-breathing propulsion engine was modeled using COMSOL Multiphysics® software. This type of flow field can be found in a dual-mode scramjet engine. After creating the geometry, a 2D CFD simulation was run using the High Mach Number Flow ... Read More

Hydrophone Acoustic Receiver Modeling: Turbulent Flow Modeling and Acoustic Analysis

D. Groulx[1], A. Bharath[1], S. Campbell[1]
[1]Department of Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

The field of underwater acoustics research is constantly growing with the ongoing improvement of acoustic measuring techniques. An acoustic hydrophone receiver is a passive listening device which is widely used in biological research and sonar technology. The hydrophone however suffers ... Read More

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 ...
