Exchange-Biased multi-ring Planar Hall Magnetoresistive Sensors with nT resolution in Non-Shielded Environments
Jan Schmidtpeter, Proloy Taran Das, Yevhen Zabila +4
Planar Hall magnetoresistive sensors (PHMR) are promising candidates for various magnetic sensing applications due to their high sensitivity, low power consumption, and compatibili…
Current Tomography -- Localization of void fractions in conducting liquids by measuring the induced magnetic flux density
L. Krause, N. Kumar, T. Wondrak +3
A novel concept of a measurement technology for the localization and determination of the size of gas bubbles is presented, which is intended to contribute to a further understandi…
Learning to reconstruct the bubble distribution with conductivity maps using Invertible Neural Networks and Error Diffusion
Nishant Kumar, Lukas Krause, Thomas Wondrak +3
Electrolysis is crucial for eco-friendly hydrogen production, but gas bubbles generated during the process hinder reactions, reduce cell efficiency, and increase energy consumption…
The Multivariate Extension of the Lomb-Scargle Method
Martin Seilmayer, Ferran Garcia Gonzalez, Thomas Wondrak
The common methods of spectral analysis for multivariate (-dimensional) time series, like discrete Frourier transform (FT) or Wavelet transform, are based on Fourier series to d…
Visualization of the global flow structure in a modified Rayleigh-Benard setup using contactless inductive flow tomography
Thomas Wondrak, Josef Pal, Frank Stefani +2
Rayleigh-Benard convection is not only a classical problem in fluid dynamics but plays also an important role in many metallurgical and crystal growth applications. The measurement…
Forward and inverse problems in fundamental and applied magnetohydrodynamics
Andre Giesecke, Frank Stefani, Thomas Wondrak +1
This Minireview summarizes the recent efforts to solve forward and inverse problems as they occur in different branches of fundamental and applied magnetohydrodynamics. As for the…
Numerical simulation of the Tayler instability in liquid metals
Norbert Weber, Vladimir Galindo, Frank Stefani +2
The electrical current through an incompressible, viscous and resistive liquid conductor produces an azimuthal magnetic field that becomes unstable when the corresponding Hartmann…
Integral equations in MHD: theory and application
Frank Stefani, Mingtian Xu, Gunter Gerbeth +1
The induction equation of kinematic magnetohydrodynamics is mathematically equivalent to a system of integral equations for the magnetic field in the bulk of the fluid and for the…
