Light Management Optimization of Upconversion-Based Solar Cell Using Genetic Algorithms

J. Bork¹, M. F. Doty¹, J. M. O. Zide¹
¹University of Delaware, Newark, DE, USA

We demonstrate a COMSOL Multiphysics®-based approach to light management for upconversion-based solar cells (UBSCs). Single-junction solar cells are of high importance to sustainable energy production, however the cells are limited in their performance by the bandgap of the solar cell. ... Read More

Aquifer Pumping Test Evaluation: 1D Classical vs. 2D Numerical Solutions

E. Holzbecher¹
¹German University of Technology in Oman

In a pumping test the drawdown of the water table in a piezometer is recorded, as response to pumping from a nearby well. Pumping tests belong into the common toolbox of hydro-geologists, used to obtain basic parameters for aquifer characterization. There are various approaches to ... Read More

Simulation of Basal Body Deformation in Tetrahymena Thermophila

L. Woodhams¹, Y. Shen¹, P. V. Bayly¹, A. D. Junker², A. J. Soh², C. Pearson²
¹Washington University in St. Louis, St. Louis, MO, USA
²University of Colorado Anschutz, Aurora, CO, USA

COMSOL® models of basal body deformation using the Beam Interface are compared to electron tomograms of Tetrahymena thermophila basal bodies high-pressure frozen while undergoing beating deformation. This approach provides insight into the nanoscale structures and internal forces ... Read More

Inverse-Design in Large Photonic Gratings Enabling Efficient Photonic-to-Free-Space Mode Coupling

A. Yulaev¹, D. A. Westly², Vladimir A. Aksyuk²
¹Department of Chemistry and Biochemistry, University of Maryland, College Park, MD, USA
²PML, National Institute of Standards and Technology, Gaithersburg, MD, USA

Realization of an efficient coupling between photonic sub-micrometer size modes and hundred micrometer wide free-space beams remains a main engineering hurdle to a wider acceptance of miniaturized chip-scale atomic and bio systems. The major obstacle comes from a gigantic mode mismatch ... Read More

[1]Raychem Innovation Centre, India
[2]Raychem Innovation Center, India

Cable joints are used for insulation of open part joints of high-voltage and large-capacity power lines. Cable joint protects conductor joint against moisture, dust ingress along with mechanical and electrical protection. Cable joint material consist of the three different layers ... Read More

3D Magneto-Structural Analysis of Magnetic Pulse Welding

A. Alli[1], B. Doshi[1]
[1]Institute for Plasma Research, PO: Bhat, Gandhinagar, INDIA, India

In this study, for the first time, we have carried out three dimensional transient magnetostructural analysis of a Magnetic Pulse welding (MPW) system which welds two tubular work pieces of dissimilar conducting materials. For this purpose a finite element model (FEM) is developed using ... Read More

Towards Automatic Defect Recognition using Active Infrared Thermography, COMSOL Multiphysics® and Machine Learning

P. Tudosa[1], D. Billson[1], D. Hutchins[1]
[1]University of Warwick, United Kingdom

Active Infrared Thermography (IRT) is a family of non-destructive testing (NDT) techniques used for the detection of surface and buried defects in a wide range of materials. The method is robust and sensitive enough to be used even in harsh industrial environments However, the ... Read More

A Fast, Simple, and Low-Cost Method for Measuring the Stress-Strain Behavior of Metallic Materials, Enabled by the COMSOL® Application Builder

[1]Plastometrex and Double Precision Consultancy, United Kingdom
[2]Plastometrex and University of Cambridge, United Kingdom

This presentation concerns a novel technique ("Indentation Plastometry") for the rapid and versatile measurement of the plasticity and strength characteristics of metallic materials using indentation data. The methodology has recently been developed by former scientists from the ... Read More

Characterization of The Physical Properties of Silicone

R. Paridant[1], R. Rozsnyo[2], T. Goldhorn[1]
[1]Fischer Connectors, Switzerland
[2]Haute École du paysage, d'ingénierie et d'architecture (hepia), Switzerland

The following study was conducted to model the different behaviors of a material. The studied material is part of the elastomer’s family and is used in a wide temperature range from -55 ° C to + 135 ° C. This large temperature amplitude will generate behaviors strongly dependent on the ... Read More

Parametric Study on Thermal Properties of a PMSM Motor in Cryogenic Environment Using COMSOL Multiphysics®
