Heat Transfer and Phase Change

Introducing Novel Convergent Geometries to Enhance Pipe Flow Convective Heat Transfer

A. Al-Sammarraie[1], K. Vafai[1]
[1]University of California, Riverside, USA

A wide variety of engineering applications, such as electronics, solar collectors, and internal combustion engines produce heat. This heat can be a positive or negative aspect for a particular application. Enhancing heat transfer has encouraged many researchers to investigate various ... Read More

Simulating Obscurants Under High Energy Laser Illumination

S. Du[1], A. Strikwerda[2], J. Miragliotta[2]
[1]Winston Churchill High School, USA
[2]Johns Hopkins University Applied Physics Lab, USA

Here we present a simulation for evaluation of novel obscurant candidates under high-energy laser (HEL) illumination. This approach incorporates thermal modeling into obscurant characterization, allowing for evaluation of the temperature increase of the candidate obscurants as well as ... Read More

Transient Thermal Performance of Three Steel Stud Wall Assemblies

M. Ghobadi[1]
[1]National Research Council of Canada, Canada

As a part of the Pan-Canadian framework for clean growth, Canada is intent on meeting its 2030 emission targets for which 17% of Canada’s total Green House Gas emissions come from buildings. Given this challenge, emphasis is being placed on developing building designs having greatly ... Read More

Finite Element Modelling and Simulation Tools for Investigation of the Process and Materials 3D-Printed by Selective Laser Melting

H. Jean Willy[1], X. Li[1], J. Ding[1]
[1]National University of Singapore, Singapore, Singapore

Selective Laser Melting (SLM), like many other additive manufacturing techniques, offers flexibility in design expected to become a disruption to the manufacturing industry. The current cost of SLM process does not favor a try-and-error way of research; which gives more room for ... Read More

Undergraduate Research on Applications of Thermoelectric Generators

D. Buna[1], C. Brisson[1], E. Almberg[1]
[1]Ramapo College of New Jersey, USA

Heat waste harvesting with thermoelectric systems is a clean, environmentally friendly energy producing option among several methods currently considered. The present study investigates the ability of COMSOL Multiphysics® simulation software to develop models that generate data in good ... Read More

Flow Calorimetry Modeling With Heat Transfer Module

J. Pham[1], E. Ziehm[1], M. Bergshchneider[2], S. Barot[2], G. Miley[1], Y. Koyake[1], B. Peecher[3]
[1]University of Illinois at Urbana-Champaign, USA
[2]Industrial Heat LLC, USA
[3]Industrial Heat LLC, Colombia

We used COMSOL Multiphysics® simulation software to model mass flow calorimetry in a metal-hydride chemisorption reaction. Using a reaction chamber with 100W input, we measured the temperature of flowing water in contact with the chamber and calculated the heat output of our reaction. ... Read More

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
