Thermal Analysis of Dry Type Power Transformer under Effect of Linear and Nonlinear Loads

R. G. Mafra [1],
[1] Universidade Federal de Itajubá, Itajubá, MG, Brazil

The thermal performance of the dry type power transformers is directly connected to the internal heat source caused by electrical losses. Thus, it is necessary to evaluate the temperatures reached by the transformer core to ensure optimum operation. This paper presents a detailed ... 詳細を見る

Simulation of Electro-Thermal Transients in Superconducting Accelerator Magnets

L. Bortot [1], M. Maciejewski [2], M. Prioli [1], B. Auchmann [3],
[1] CERN, Geneva, Switzerland
[2] CERN, Geneva, Switzerland; Lodz University of Technology, Lodz, Poland
[3] CERN, Geneva, Switzerland; Paul Scherrer Institute, Zurich, Switzerland

The paper presents the application of COMSOL Multiphysics® software to the modelling of superconducting accelerator magnets. A 2D magneto-thermal model is developed, using an equivalent magnetization formulation to take into account the eddy-currents’ effects. Due to the model ... 詳細を見る

Thermal Analysis on Module Level in an Automotive Battery Package

Z. Wu [1], H. Kemper [1],
[1] Energy Storage Systems, FH Aachen, Aachen, Germany

Vehicles with battery as energy storage fascinate more and more people. Meanwhile, more questions are surfaced – How to ensure a safe operation of the battery package? How long could the cycle life of a battery package reach? Can a battery package be operated in any environmental ... 詳細を見る

Finite Element Modeling of Dispersion and Thermal Noise in Whispering-Gallery Mode Cavities

N. M. Kondratiev [1], M. L. Gorodetsky [1]
[1] Russian Quantum Center (RQC), Moscow, Russia

This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence ... 詳細を見る

Design of a Heat Trap for Optimal Heat and Current Conduction on Soldering Pads

F. Figueroa [1], P. Aguirre [1],
[1] STW, Sensor Technik Wiedemann GmbH, Kaufbeuren, Germany

This poster presents an evaluation study of a couple of heat trap designs, analyzing the generation of Joule heating and heat dissipation characteristics. Through parametric simulations of the heat traps varying geometries, it is possible to see the generated temperature difference at a ... 詳細を見る
