Lorentz Force Velocimetry measurements using HTS bulk magnet system. - In: Workshop Elektroprozesstechnik, (2017), 9, insges. 8 S.

An experimental demonstration of the Lorentz force velocimetry (LFV) technique using high-temperature superconducting (HTS) bulk magnet system (MS), acting as trapped field magnets, is reported. Besides the experimental results on the Lorentz force, FL, induced by a vertically aligned cylindrical moving metal rod through the oppositely arranged HTS-MS, the HTS-MS design as well as activation procedure, including refrigeration and magnetization, along with further suggestions for improvements are discussed.

Elektromagnetische Eigenschaften und Anwendungspotentiale von submikroskaligen, substituierten Hexaferritpulvern. - In: Workshop Elektroprozesstechnik, (2017), 8, insges. 17 S.

Im vorliegenden Beitrag werden Mikrowellen absorbierende AII/BIV substituierte Bariumhexaferrite (BHF) in einer glasigen Matrix durch Schnellkühlung der Schmelze mit der Zusammensetzung 40 Mol-% BaO + 27-(y+x) Mol-% Fe2O3 + x Mol-% AIIO + y Mol-% BIVO2 + 33 Mol-% B2O3 und anschließender bottom-up-Steuerung der Keimbildung und des Kristallwachstums (Glaskristallisationstechnik) synthetisiert. Dabei werden Substituent (paramagnetische Kationen: MnII, FeII, CoII, diamagnetisches Kation: TiIV) und Temperbedingungen (Temperatur, Haltezeit) systematisch variiert und wesentliche Struktur-Eigenschafts-Beziehungen zur Synthese der substituierten Bariumhexaferrite aufgeklärt. Die synthetisierten BHF-Pulver sind für die Herstellung von Bond/ Disbond-on-Command Klebstoffen und von maßgeschneiderten Absorbermaterialien sowie für sensorische magnetische Anwendungen geeignet. Die Herstellung der BHF-Pulver wurde im Labormaßstab erfolgreich getestet. Lösungsansätze für die industrielle Produktion werden vorgestellt.

Development of electromechanical principle for wet and dry milling. - In: Proceedings of the VIII International Scientific Colloquium Modelling for Materials Processing, (2017), S. 223-229

The paper presents a novel electromechanical principle for wet and dry milling of different materials in which the milling beads are moved under time- and local-variable magnetic field. It is shown possibility to optimize the milling process in such milling machine by simulation of the gradient of vector electromagnetic field distribution in the working chamber. The mathematical model and simulation methods based on standard software packages are worked out. The results of numerical simulations and experimental measurements of electromagnetic field in working chamber of the developed and manufactured laboratory plant are in good correlation. With the obtained operating parameter dry milling experiments with crushed cement clinker and wet milling experiments of organic agents in the laboratory plant are executed and the results are discussed.

High-temperature superconducting magnet systems for Lorentz Force Velocimetry. - In: XVIII International UIE-Congress - Electrotechnologies for Material Processing, ISBN 978-3-8027-3095-5, (2017), S. 356-361

Lorentz Force Velocimetry (hereafter abbreviated as LFV) - a technique for flow rate measurement of conducting liquid. Remarkably, due to contactless measuring, this method is advantageous for aggressive media, such as molten salts and glass melts. However, These fluids possess a weakly electrical conductance and slow velocity, resulting a small Lorentz force (in [my]N range) and, consequently, the tiny resolution. The high-temperature bulksuperconducting (HTS) magnet system (MS) is proposed to integrate the Lorentz Force Velocimetry setup rendering significantly superior magnetic field. In order to implement the HTSs, acting as trapped field magnets, the appropriate refrigeration must be considered.
