An Analytical Thermal Model for Coaxial Magnetic Gears Considering Eddy Current Losses

Modelling
This work presents an analytical 2D model for estimating eddy current losses in the permanent magnets (PMs) of a coaxial magnetic gear (CMG), with a focus on loss minimization through magnet segmentation.

A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers

Advanced Science, EarlyView.
Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...

Ultra-high reduction of eddy current losses in additively manufactured soft magnetic material via a novel dense-stack lamination architecture

Materials & Design
Eddy current losses in motors and transformers are undesirable because they degrade energy efficiency. Several methods have been proposed to reduce it in additively manufactured (AM) soft magnetic materials but suffer from low design efficiency and ...

Eddy current losses in transformer windings

, 2020
Målet med denne masteroppgaven er å undersøke en semi-analytisk tapberegningsmetode, spesielt når man tar hensyn til virvelstrømstap i transformatorviklinger. Dette gjøres gjennom sammenligninger mellom simulerte og målte resultater, og gjennom sammenligninger av målte og nominell data fra produsenten.

Exceptional Antimodes in Multi‐Drive Cavity Magnonics

Advanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

A new drag and lift correlation for spherocylinders from fully resolved Immersed Boundary Method

AIChE Journal, EarlyView.
Abstract Many industrial processes deal with non‐spherical particles, e.g., mineral mining and biomass conversion. It is crucial to understand the particles' hydrodynamics to control and optimize these processes. To extend the current state‐of‐the‐art from arrays of spherical particles to spherocylindrical particles, we performed extensive particle ...
