Smart Radiator Upgrade (Super Smart with Natural Gas)

E. Bozelie[1], P. Bruins[1]
[1]Saxion University Enschede, Enschede, The Netherlands

In heating upgrades, most attention is paid to the boiler. When upgrading to HR++-boilers (eff of 107%) however, difficulties may occur since the high efficiency boilers are designed for water temperatures around 40°C, while the old radiators are designed for water temperatures higher ...

[2]Department of Nuclear, Plasma & Radiological Engineering, University of Illinois at Urbana - Champaign, Urbana, IL, USA
[3]University of Illinois at Urbana - Champaign, Urbana, IL, USA

A COMSOL Multiphysics® model of our apparatus has been created in order to simulate the pressurizations of our nanoparticles by Deuterium. Using reference measurements during a cooling process, we calibrated the model so that its thermal aspects reflect the ones of our experimental set ... Read More

Modeling and Testing of Carbon-Fiber Doubly-Resonant Underwater Acoustic Transducer

A. Morozov[1]
[1]Teledyne Technologies Inc., Falmouth, MA, USA

This paper describes the COMSOL Multiphysics® simulation and the test of a low-frequency (500Hz) sound source for long-range acoustic communications. This design uses innovative carbon-fiber composite materials.To meet the demand for the frequency range the doubly resonant organ pipe ... Read More

Finite Element Analysis of Superconductive Tape by Using T-Ω Formulation

H. Arab[1], S. Memiaghe[1], C. Akyel[1]
[1]Ecole Polytechnique of Montreal, Montreal, QC, Canada

This paper deals with a numerical modelling technique based on finite elements method for computing magnetic field and current density distributions in high temperature Superconducting (HTS) tapes. The model is developed using the T-ῼ formulation for which the degree of freedom (DOF) and ... Read More

A Practical Method to Model Complex Three-Dimensional Geometries with Non-Uniform Material Properties Using Image-based Design and COMSOL Multiphysics®

J. Cepeda[1], S. Birla[2], J. Subbiah[2], H. Thippareddi[1]
[1]Department of Food Science & Technology, University of Nebraska, Lincoln, NE, USA
[2]Department of Biological Systems Engineering, University of Nebraska, Lincoln, NE, USA

Geometries with heterogeneous material properties are typically defined as a set of multiple parts, each part representing a different material. However, assembling or defining the individual parts of complex geometries can be difficult. A practical method based on image-based mesh ... Read More

Simulation of Formwork Filling by Cement Fluid: The Effect of the Formwork Structure on Yield-stress Fluid

J. Park[1], N. Banerjee[1], M. Alfi[1], D. Feys[1]
[1]Missouri University of Science & Technology, Rolla, MO, USA

The flow of self-consolidating concrete (SCC) in formwork fillings was simulated as the flow of a single phase yield-stress fluid between two infinite plates by COMSOL Multiphysics®. The flow of SCC with varied rheological properties (yield stress and plastic viscosity) was verified in ... Read More

Equation Based Heat and Mass Transfer in Porous Media

S. Pemberton[1], K. Ekici[1], R. Arimilli[1]
[1]The University of Tennessee, Knoxville, TN, USA

Perspiration during intense physical activity is an essential part of human thermoregulation. Clothing affects the cooling rate of the body. Heat and water vapor are coupled through evaporation and transported through the fabric. A model of the above system was developed for fabrics of ... Read More
