Simulation of High Temperature Superconducting Bulks Magnetized by Pulsed Field Magnetization with an Electromagnetic-Thermal Coupled Model

, 2015
High temperature superconducting (HTS) bulks can be magnetized to become powerful trapped field magnets (TFMs), which are promising for high-performance electrical applications. To magnetize such TFMs, pulsed field magnetization (PFM) is supposed to substitute field cooling (FC) to provide in situ magnetization. However, the heat generation during PFM,

Heat transport in harmonic oscillator systems with thermal baths: application to optomechanical arrays

New Journal of Physics, 2015
We investigate the transport of phonons between N harmonic oscillators in contact with independent thermal baths and coupled to a common oscillator, and derive an expression for the steady state heat flow between the oscillators in the weak coupling ...

Experimentally validated numerical model of coupled flow, thermal and electromagnetic problem in small power electric motor

Computer Assisted Methods in Engineering and Science, 2017
This paper describes results of the mathematical modelling of the steady-state thermal phenomena taking place in a Fracmo 240 W DC electric motor. The model of the motor was defined in the ANSYS Fluent software to predict flow and temperature fields ...

Single-particle machine for quantum thermalization

, 2010
The long time accumulation of the \textit{random} actions of a single particle "reservoir" on its coupled system can transfer some temperature information of its initial state to the coupled system.

Simulation of Stacks of High Temperature Superconducting Coated Conductors Magnetized by Pulsed Field Magnetization Using Controlled Magnetic Density Distribution Coils

, 2015
High temperature superconducting (HTS) stacks of coated conductors (CCs) can work as strong trapped field magnets (TFMs) and show potential in electrical applications. Pulsed field magnetization (PFM) is a practical method to magnetize such TFMs, but due
