Heat Transfer and Phase Changex

An Overpressure Furnace: Understanding Performance and Analysis-Led Design Improvements

E. Bosque[1], U. Trociewitz[1], L. English[1]
[1]Florida State University, USA

Bi2Sr2CaCu2O8+δ (Bi 2212) is being developed as a high temperature superconductor (HTS) technology with practical use in ultra-high field (+30 T) magnets. A critical processing step for this conductor is a ~890 degC heat treatment at elevated pressure (~50 atm). The reaction of this ... Read More

Three-Dimensional Mixed Convection in a Rectangular Duct

A. Oluwade[1], T. Onyenze[1], E. Glakpe[1]
[1]Howard University, USA

Numerical study of fluid flow and heat transfer in a finite three-dimensional rectangular, horizontal duct of length to width, and length to height ratio of 12:1 is investigated in this study. The left wall of the duct is uniformly heated while the right, top, and bottom walls are ... Read More

Thermal and Flow Simulation of a High Temperature Printed Circuit Heat Exchanger

Q. Zhu[1], X. Tan[1], B. Barari[1]
[1]MIT, USA

Printed circuit heat exchanger (PCHE) is a key component in many energy and power systems, such as concentrated solar power plant, nuclear power plant, aircraft, etc. In this paper, the thermal and fluid performance of a lab-scale PCHE is analyzed using COMSOL Multiphysics® simulation ...

Coupling the Transfer of Light with the Transfer of Heat using a Diffusion Approximation

T. Dreeben[1], A. Lenef[1]
[1]OSRAM Opto Semiconductors, USA

High-powered solid-state lighting uses ceramic materials for conversion of impinging blue pump light into bright longer-wavelength luminescence. This luminescence combines with an unconverted portion of the blue pump light to provide a white light spectrum. As the conversion efficiency ... Read More

CFD Modeling of a 4-He Evaporation Refrigerator for Polarized Target Experiments

D. Aliaga[1], N. Santiesteban[2], P. Bunout[3], W. Brooks[1], K. Slifer[2], E. Long[2], D. Ruth[2], C. Romero[1]
[1]Universidad Tecnica Federico Santa Maria, Chile
[2]University of New Hampshire, USA
[3]Universidad Tecnica Federico Santa Maria, USA

We here present a Computational Fluid Dynamics (CFD) model performed with COMSOL Multiphysics® simulation software as part of a collaboration with the Polarized Target Research Group at the University of New Hampshire (http://nuclear.unh.edu/research/polarized-target-lab/). By coupling ... Read More

Thermal Analysis of Electronics Cabinet

J. Crompton[1], K. Koppenhoefer[1], J. Thomas[1], L. Gritter[1], N. Molnar[2], K. Orlando[2]
[1]AltaSim Technologies, USA
[2]Rockwell Automation, USA

Increasing demand for enhanced functionality and smaller form factor has led to significant increases in the power consumed by today’s electronic control modules. Consequently, improved thermal management of individual components and control modules is now a primary consideration to ... Read More

Computational Modeling of Nanoparticle Heating for Treatment Planning of Plasmonic Photothermal Therapy in Pancreatic Cancer

S. Manrique-Bedoya[1], C. Moreau[2], S. Patel[2], Y. Feng[1], K. Mayer[1]
[1]University of Texas at San Antonio, USA
[2]UT Health San Antonio, USA

Pancreatic cancer is one of the deadliest cancers, with a 7% survival rate at five years from diagnosis. The limited number of treatment options for patients who are diagnosed with late-stage disease is a major contributor to this problem. Therapeutic modalities such as radiofrequency ... Read More

Analysis of the Absorption Phenomena through the Use of Finite Element Method

M. Robles-Agudo[1], R. Velázquez-Hernández[1], P. Duran[1], I. Rojas-Rodríguez[1]
[1]UNIVERSIDAD TECNOLÓGICA DE QUERETARO, Mexico

We present a numerical model using the Finite Element Method (FEM) with COMSOL Multiphysics® simulation software to characterize Beer-Lambert law. The Heat Transfer Module was used in the program developed to calculate absorption and propagation of heat wave phenomena in a material. ... Read More

Effects of Mold-Casting Contact on Solidification in Continuous Casting

E. Gutierrez-Miravete[1]
[1]Rensselaer at Hartford, USA

This communication describes a model created to investigate the effect of mold-metal contact on casting solidification in the continuous casting process. The Heat Transfer and Solid Mechanics modules of COMSOL Multiphysics® simulation software are used to construct a non-linear finite ... Read More

Assessing Reliability of Embedded Resistor Designs in Integrated Circuit

R. Wulandana[1], P. Wang[1], L. McCary[1], S. Alzeq[1]
[1]State University of New York (SUNY) at New Paltz, USA

Localized Joule heating within integrated circuit (IC) chips is the leading cause of non-uniform temperature distribution within the circuit structure of the chips. Such variation in temperature enhances the biased diffusion of metal atoms along current carrying interconnects, a ... Read More
