A New Approach to Measure Fundamental Microstructural Influences on the Magnetic Properties of Electrical Steel using a Miniaturized Single Sheet Tester

Nora Leuning, Martin Heller, Markus Jaeger +2

Magnetic properties of electrical steel are usually measured on Single Sheet Testers, Epstein frames or ring cores. Due to the geometric dimensions and measurement principles of th…

Microstructure-dependent magnetic properties of iron silicon single, bi- and oligo-crystals measured with a miniaturised Single-Sheet-Tester

Martin Heller, Nora Leuning, Marlies Reher +2

Electrical iron silicon steel is the most commonly used soft magnetic material in electrical energy conversion and transmission, and its demand is expected to increase with the nee…

Deformation of micrometer and mm-sized Fe2.4wt.%Si single- and bi-crystals with a high angle grain boundary at room temperature

Martin Heller, James S. K. -L. Gibson, Risheng Pei +1

Plasticity in body-centred cubic (BCC) metals, including dislocation interactions at grain boundaries, is much less understood than in face-centred cubic (FCC) metals. At low tempe…

Multi-directional sorting modes in deterministic lateral displacement devices

Brian R. Long, Martin Heller, Jason P. Beech +3

Deterministic lateral displacement (DLD) devices separate micrometer-scale particles in solution based on their size using a laminar microfluidic flow in an array of obstacles. We…

A theoretical analysis of the resolution due to diffusion and size-dispersion of particles in deterministic lateral displacement devices

Martin Heller, Henrik Bruus

We present a model including diffusion and particle-size dispersion for separation of particles in deterministic lateral displacement devices also known as bumper arrays. We determ…

Particle motion in microfluidics simulated using a Femlab implementation of the level set method

Martin Heller, Henrik Bruus

We implement the level set method for numerical simulation of the motion of a suspended particle convected by the fluid flow in a microchannel. The method automatically cope with t…
