Time-Harmonic Modeling of Squirrel-Cage Induction Motors: A Circuit-Field Coupled Approach

R. Escarela-Perez[1], E. Melgoza[2], and E. Campero-Littlewood[1]

[1]Universidad Autonoma Metropolitana - Azcapotzalco, Departamento de Energia, México, D.F., Mexico
[2]Instituto Tecnologico de Morelia, Morelia, Mich., C.P., Mexico

Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... En savoir plus

Ultrasound Pressure Field of a Resonating Piezoelectric Membrane with Three Excitation Electrodes

V. Tzanov [1], E. Ledesma [1], F. Torres [1], N. Barniol [1],
[1] Universitat Autonoma de Barcelona, Spain

Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... En savoir plus

Numerical modelling of slot die coating

Slot die coating is a method to apply thin films of materials on a substrate. The geometry of the die affects the flow of the material within it and the quality of the layer being deposited. The die can also be blocked along the width for multiple parallel depositions or to deposit on ... En savoir plus

Coupling Multiscale Phenomena in Alkaline Electrolyzer Stack Simulation Using Reduced Order Models

Priit Priimägi¹, Jonathan Dallaire², Kevin Van Droogenbroek³, Joris Proost³, Kresten Juel Jensen², Rainer Küngas¹
¹Stargate Hydrogen Solutions OÜ, Tallinn, Estonia
²Resolvent Denmark P/S (Certified COMSOL Consultant), Måløv, Denmark
³Division of Materials and Process Engineering, Université catholique de Louvain, Louvain-la-Neuve, Belgium

Porous three-dimensional electrodes are promising for use in alkaline electrolyzer due to their high surface area. Nickel foams, specifically, serve a dual purpose as both a current collector and an active working electrode, enhancing current density and boosting hydrogen production[1]. ... En savoir plus

3-D Modeling of Light, Flow, Mass and Heat Transfer in Coral Colonies

Martinez Jimenez Fernan David¹, Murthy Swathi², Picioreanu Cristian¹, Kühl Michael²
