Investigations on Polydisperse gas phase - Dynamic
No full textThis repository contains sequences of CT images of the two-phase flow in a bubble column consisting of a DN100-PN4 PVC pipe filled with water. As measurement system the ultrafast electron beam X-ray computed tomography scanner was applied in dual plane scanning mode with a dual-imaging frequency of 2,000 Hz. Data containers starting with “SingleBubble” contain image sequences of scans where a single bubble was injected at the bottom of the column using a magnetically operated valve which was open for the time specified in the directory name. Data containers starting with “PolydisperseDynamic” contain image sequences of scans where a background flow with 01 to 20 sl/min was induced via a needle sparger in addition to the single bubble (as described before). During each “PolydisperseDynamic” scan, the scan position was adapted to track the large bubble. The HDF5 files hold the reconstructed image data (dataset “reco”), each images scanning plane (dataset “plane”), and each images vertical scan position (dataset “scanPosition”)

Data publication: Self-induced Floquet magnons in magnetic vortices
No full textThis data publication contains the data for our publication "Self-induced Floquet magnons in magnetic vortices". The dataset is structured in folders corresponding to the different figures in the paper. Folder Fig-2 contains the simulated and experimental spectra measured with Brillouin-light-scattering microscopy. The experimental spectra contain the data integrated for the measurement positions described in the methods section. Folder Fig-4 contains the evaluated numerical data presented in the corresponding panels. Folder Fig-5 contains the experimental spectra measured with Brillouin-light-scattering microscopy as a function of power and time. Folder FIG-S1 contains the log file for the sample fabrication and scanning electron microscope (SEM) images. Important note for the SEM images: When acquiring the SEM images, the calibration of the Raith150 tool was off momentarily. This resulted in recording the wrong scale bars with the images. The structure dimensions are known from the design file and were confirmed at another time after adjusting the calibration. Folder S2 contains the BLS spectra for different frequencies of the gyration excitation. Folder S4 and S5 contain the simulated spectra for the respective shown panels. Folder S6 contains the power sweeps and time trace BLS data. Fig S9 contains the shown BLS data
FVV1455: CFD Simulation of Droplet Separators
No full textFor industrial applications, the two-fluid model is preferred due to its
efficient modelling of small-scale interfaces. Whereas, a thin film model,
based on a long wave approximation, is used for the unresolved interfaces to
obtain the film features by solving the 2D Navier-Stokes equations for wall
films. Within the project, the target is to develop an experimentally validated
3D-CFD model to investigate the separation efficiency of droplet separators for
fuel cell systems. A hybrid model is developed, which couples the two-fluid
model with a thin film model via mass transfer terms for droplet deposition,
droplet entrainment and film separation. A two-way coupling between droplets
and the thin film is established using mass and momentum source terms, derived
analytical and from available experiments. The droplet separator is an essential
component of an automotive fuel cell system that segregates a significant amount
of liquid fractions from the air-water mixture. The flow dynamics inside a
droplet separator consist of a dispersed gas and liquid with a wall adhered
thin liquid film. The modelling is divided into the following stages due to the
complex fluidic phenomenon inside a generic droplet separator:
Droplet deposition model,
Film separation model,
Film transition model, and
Population balance model.
In order to systematically validate numerical models and methods that predict
the characteristics of films and the separation efficiencies of droplet
separators, high-quality experimental data must be carefully acquired. For the
experimental investigations an air-water two-phase flow loop was set up. The
flow loop is extensively instrumented in order to provide precise data on the
respective operating conditions such as mass low and pressure drop. The
following advanced measurement techniques have been applied:
HZDR's flow microscope to investigate droplet flow,
HZDR's advanced microfocus X-ray tomograph to visualize the liquid films, and
radioscopic imaging to investigate dynamic flow processes.
The generic droplet separator was extensively tested under varying operating
conditions at a total of 27 measurement points covering a wide range of mostly
wavy and annular inlet flow conditions. The resulting comprehensive set of
experimental data provides an excellent basis for the development and validation
of numerical design tools required by the industry.The research project was self-financed (FVV funding no. 1455) by the FVV e.V

Data publication: Effect of Helium Ion Implantation on 3C-SiC Nanomechanical String Resonators
No full textThe file "figures.hdf5" contains all numbers plotted in the figures of the main manuscript. Each entry in the first hierarchy level of the file, e.g. "Figure 2a", corresponds to one subfigure. Each entry in the second hierarchy level (if existent) corresponds to one of the curve/subset of the the respective figure, e.g. if curves for multiple fluences are plotted. The innermost hierarchy level contains the data arrays. The dataset name corresponds to the axis label and units. The file "analyzed.hdf5" contains frequencies, quality factors, stress and Young's modulus fit results for each measured nanostring device on each measured sample. The first hierarchy level represents the sample (A or B). The second hierarchy level represents the accumulated implantation fluence that the sample has seen before the respective measurements. The third hierarchy level represents the write field, i.e. string array index, on the chip (0-3) and the fourth hierarchy level represents the string length within the write field. Each length exists exactly once in each write field. The innermost hierarchy level contains arrays of mode number, frequency, quality factor and "raw data indices" (see next paragraph) representing each measured resonance. The fields Young's modulus and pre-stress are scalars containing the respective fit result and its uncertainty. The file "raw.hdf5" finally contains all raw spectra. The first hierarchy level corresponds to unique indices of the respective measurement. This is intended as a look up table for the "raw data indices" of the "analyzed.hdf5" file. Using the index found in the "analyzed.hdf5", one can obtain the raw frequency sweep data and metadata. The file "srim-VACANCY.txt" is the vacancy output file of the SRIM simulation discussed in the main manuscript
