Nanoscale Heat Transfer using Phonon Boltzmann Transport Equation

S. Sihn[1,2], and A.K. Roy[2]

[1]Air Force Research Laboratory, Wright-Patterson Air Force Base, Dayton, Ohio, USA
[2]University of Dayton Research Institute, Dayton, Ohio, USA

COMSOL Multiphysics was used to solve a phonon Boltzmann transport equation (BTE) for nanoscale heat transport problems. One dimensional steady-state and transient BTE problems were successfully solved based on finite element and discrete ordinate methods for spatial and angular ... En savoir plus

Drying of Corn Kernels: From Experimental Images to Multiscale Multiphysics Modeling

P. Takhar[1], and S. Zhang[2]

[1]Texas Tech University, Lubbock, Texas, USA
[2]Visualization Sciences Group Inc., Burlington Massachusetts, USA

This work demonstrated the importance and feasibility of experimental image to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling based on 3D experimental image reconstruction contributes to the preservation of ...

Solid-Liquid Phase Change Simulation Applied to a Cylindrical Latent Heat Energy Storage System

D. Groulx[1], and W. Ogoh[1]

[1]Mechanical Engineering Department, Dalhousie University, Halifax, Nova Scotia, Canada

One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... En savoir plus

Wall Effects in Convective Heat Transfer from a Sphere to Power Law Fluids in Tubes

D. Song[1], R. Gupta[1], and Chhabra[2]

[1]West Virginia University, Morgantown, West Virginia, USA
[2]Indian Institute of Technology, Kanpur, India

Heat transfer from a sphere having a uniform temperature and falling axially in a cylindrical tube filled with an incompressible power-law liquid is numerically investigated. The governing equations for simultaneous flow around a confined sphere and heat transfer to power-law fluids were ... En savoir plus

Multiphysics Simulation of a Packed Bed Reactor

A.E. Varela[1], and J.C. García[1]

[1]University of Carabobo, Valencia, Venezuela

Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... En savoir plus

COMSOL in a New Tensorial Formulation of Non-Isothermal Poroelasticity

A. Mario-Cesar Suarez[1], and V. Fernando Samaniego[2]

[1]Faculty of Sciences, Michoacan University, Morelia, Mich., Mexico
[2]Faculty of Engineering, National University of Mexico, Mexico City, Mexico

The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... En savoir plus

Periodic Near-field Enhancement on Metal-Dielectric Interfacial Gratings at Optimized Azimuthal Orientation

M. Csete[1,2], X. Hu[1], A. Sipos[2], A. Szalai[2], A. Mathesz[2], and K. Berggren[1]

[1]Research Laboratory of Electronics, Nanostructures Laboratory, Massachusetts Institute of Technology, Massachusetts, USA
[2]Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary

The effect of plasmon-wavelength scaled gratings on the surface plasmon resonance is studied experimentally and theoretically. The model samples are multi-layers containing laser fabricated gratings at bimetal-polymer interfaces. Dual-angle dependent surface plasmon resonance ... En savoir plus

Benchmarking COMSOL - Part 2: CFD Problems

Darrell Pepper
Professor of Mechanical Engineering,
University of Nevada - Las Vegas

Using COMSOL 3.5a, a set of benchmark problems requiring the use of the COMSOL Computational Fluid Dynamics (CFD) module has been simulated. Several of the problems include fluid-heat transfer interactions (Computational Heat Transfer - CHT). The four problems are: flow over a 2-D ... En savoir plus

Using Microwaves for Extracting Water From the Moon

Edwin Ethridge
Senior Materials Scientist, NASA Marshall Space Flight Center

A scientific hypothesis states that cryogenic trapped water is just under the surface of lunar soil at the poles in permanently shadowed craters. Microwave energy can be used to efficiently extract this water from permafrost. COMSOL permits calculation of the heating of simulated lunar ... En savoir plus

The Use of CFD Simulations in Learning Fluid Mechanics at the Undergraduate Level

Marc K. Smith
Professor of Mechanical Engineering, Georgia Institute of Technology

Simple, accurate CFD simulations using COMSOL Multiphysics are used in a senior-level undergraduate course as a means to explore a number of fluid flows with the intent of developing a deep understanding of the underlying fluid mechanical mechanisms involved in the flows. Students also ... En savoir plus
