Application of System Identification Methods to Implement COMSOL Models into External Simulation Environments

A.W.M. van Schijndel[1] and M. Gontikaki[1]

[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Full coupling of distributed parameter models, like COMSOL, with the lumped models often lead to very time-consuming simulation duration times. In order to improve the speed of the simulations, the idea of using system identification methods to implement the distributed parameters models ... En savoir plus

Modeling of Viscoelastic Phenomena in Concrete Structures

A. Pomarico [1], G. Roselli [1], D. Caltabiano [2],
[1] STMicroelectronics, Lecce, Italy
[2] STMicroelectronics, Agrate, Italy

A growing demand is recently emerging of sensors to be integrated in the concrete in order to measure some critical parameters, such as humidity and temperature and the internal pressure of the material. For example, by monitoring the pressure in various strategic points of the structure ... En savoir plus

Vibration and Acoustic Analysis of a Trussed Railroad Bridge under Moving Loads

R. Costley[1], H. Diaz-Alvarez[1], M. McKenna[1], A. Miller[1]
[1]U.S. Army Engineer Research and Development Center, Vicksburg, MS, USA

Two finite element models have been developed to investigate the acoustic radiation from a Pratt truss train bridge. The first model was a time dependent structural model that determined the vibration response of the structure due to two wheels, representing a single axle, moving across ... En savoir plus

Thermal Performance of the New Bioclimatic Hall of the Historical Hospital in Florence

C. Balocco, and E. Marmonti
Dipartimento di Energetica “Sergio Stecco”
Università degli Studi di Firenze
Firenze, Italy

The main aim of the present work is the study of the thermal and energy performances of the new hall of the Old St.Maria Nuova Hospital in the center of Florence (Italy). Transient simulations were carried out of the 3D model of the hall to analyse the air flow patterns, distribution and ... En savoir plus

Foundational Undergraduate Teaching and Research Tools In Thermoelectrics Using COMSOL Multiphysics®

D. Buna [1], L. Hoxha [1], D. Tafone [1]
[1] School of Theoretical and Applied Science, Engineering Physics, Ramapo College of New Jersey, Mahwah, NJ, USA

COMSOL Multiphysics® can play a crucial role in jumpstarting undergraduate research programs in physics and engineering at colleges with limited financial support and small faculty size. The engineering physics program at Ramapo College of NJ has 48 majors and 4 full time faculty with ... En savoir plus

Simulation and Verification of Coupled Heat and Moisture Modelling

N. Williams Portal[1], M. van Aarle[2], and J. van Schijndel[2]
[1]Department of Civil and Environmental Engineering, Chalmers University of Technology, SE-412 96 Göteborg, Sweden
[2]Department of Architecture, Building and Planning, Technical University of Eindhoven, Eindhoven, The Netherlands

This paper includes the implementation and comparison of two types of moisture potentials for the combined transport: the natural logarithmic of the suction pressure (LPc) and the relative humidity (RH). The finite element method has been utilized to evaluate coupled 1D thermal and ... En savoir plus

Long-term Effects of Ground Source Heat Pumps on Underground Temperature

X. Zheng[1]
[1]Wayne State University, Detroit, MI, USA

This study set up a numerical model in COMSOL Multiphysics® and simulated the underground temperature over 100 years. The long-term underground temperature around an energy pile was investigated without considering groundwater movement. Parameters and boundary conditions were examined ... En savoir plus

Enhanced Transient Modeling of Hybrid Photovoltaic Air (PVT) Module

R. Kiflemariam[1], M. Almaz[1], F. Zevallos[1], C. Lin[1]
[1]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

A 2D transient heat conduction model was created in COMSOL Multiphysics® software to study the performance of photovoltaic-thermal (PVT) water system. The model captures the variation of important environmental and system parameters such as outside temperature, solar irradiation, air ... En savoir plus

Study of Electromagnetic Shielding, a Comparison between Experiment and FEM Simulation

G. Sun [1], C. De Blasiis [1], O. Sekula [1], P. Corsaro [1],
[1] Brugg Kabel AG, Brugg, Switzerland

The loaded underground high voltage cable generates magnetic field with industrial frequency. Depending on the current rating and cable allocation, the magnetic exposure to public area may exceed the requested limit from customer. Extra shielding should then be applied. A primary FEM ...

Transient CFD Investigation of a Photocatalytic Multi-tube Reactor

S. Denys [1], J. van Walsem [1], J. Roegiers [1], S. Lenaerts [1],
[1] University of Antwerp, Antwerp, Belgium

As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a ...
