title: Computed tomography scans of 15 different carbon fiber reinforced polyamide 6 specimens (both original files (16 bit) and files of further cut scans (8 bit))

description: This dataset of scans was used in a publication that deals with the computational determination of fiber volume contents from µCT scans. Specimens from two carbon fiber reinforced polyamide 6 plaques are used that were produced in the long fiber reinforced thermoplastic direct (LFT-D) process. From the first plaque, three specimens each from both the charge and flow area of the plaque are included with dimensions of 10 mm $\times$ 10 mm $\times$ 3 mm, 20 mm $\times$ 20 mm $\times$ 3 mm and 30 mm $\times$ 30 mm $\times$ 3 mm, respectively. From the second plaque nine specimens were extracted in a regular 3 $\times$ 3 grid all with the dimensions 25 mm $\times$ 25 mm $\times$ 3 mm. Exact cutting plans can be taken from the publication. The specimens are cut out of the plaques through waterjet cutting. The material constituents, with which the final CF-PA6-LFT-D plaques were manufactured, are Zoltek PX35 commercial carbon fibers and a PA6 by the company DOMO. The scans of the first plaque were done with a Zeiss Metrotom 800 (cone-beam) μCT system at wbk Institute of Production Science at KIT with the flat panel detector PaxScan2520V with 1536 pixel $\times$ 1920 pixel. The samples of the second plaque were scanned in an YXLON-CT (Yxlon International CT GmbH, Hattingen, Germany) precision μCT system at Institute for Applied Materials (IAM-WK) at KIT with a μ-focus X-ray transmission tube with tungsten target and a PerkinElmer (Waltham, MA, USA) Y.XRD1620 flat-panel 2048 pixel $\times$ 2048 pixel detector. More details can be found in the corresponding publication.
description: The 15 scans are available as .raw- and .mhd-files, which can be read in Python with, e.g., the SimpleITK package, or in ImageJ (FIJI). The entirety of the scans are available twice: One set only has small brightness and contrast adjustments and cutting at the edges, but is otherwise in the original 16 bit data format. This set was used for the training of the convolutional neural network. The other set was cut more and is converted into 8 bit, which was used for the thresholding algorithm.

This data is part of a larger data set on congestion in the German electricity grids from 2015 to 2017. The related datasets are referenced below. The publication of this data set was supported by the German Research Foundation (DFG) as part of the Research Training Group GRK 2153: Energy Status Data - Informatics Methods for its Collection, Analysis and Exploitation.
description: The data is available for the time of 1/1/2015 until 12/31/2017 for 200 lines, which were in operation during this time. There are two different data sets, which were transformed differently to provide different possibilities for further exploration. Data set "lineloaddata50percentthreshold" has the following binary encoding: - 0 - lines having a load of up to 50 % or below of their thermal capacity limit - 1 - lines having a load of more than 50 % of their thermal capacity limit - NaN - no data available Data set "lindloaddata_70percentthreshold": - 0 - lines having a load of up to 70 % or below of their thermal capacity limit - 1 - lines having a load of more than 70 % of their thermal capacity limit - NaN - no data available The date format is (mm/dd/yyyy). Please be aware of this while reading in the data. The used separator is ',' (.csv). Every transmission line has a distinct column comprising its binary information about its congestion state as explained before. The line / column names are identical to the coding of line names 50 Hertz GmbH uses.

title: Coupled Simulation of Flow-Induced Viscous and Elastic Anisotropy of Short-Fiber Reinforced Composites

description: The present work discusses the impact of the back coupling of the fiber orientation distribution on the base flow and on the fiber orientation itself during mold filling simulations. Flows through a channel and over a backward-facing step are investigated as representative abstracted real part geometries. Different closure approximations are considered for modeling the flow induced evolution of anisotropy. Results corresponding to the decoupled approach, in which the effect of fibers on local fluid properties is neglected, build the basis of comparison. The modeling is limited to a laminar, incompressible and isothermal flow of a fiber suspension consisting of rigid short fibers embedded in an isotropic Newtonian matrix fluid. A linear, anisotropic constitutive law is used in combination with a uniform fiber volume fraction of $10\,\%$ and an aspect ratio of $10$. To evaluate the impact of back coupling and of different closure methods in view of the solid the resulting anisotropic elastic properties are investigated based on the Mori-Tanaka method combined with an orientation average scheme. Regarding the possible range of the diagonal components of the orientation tensors the pointwise difference in fiber orientation between the decoupled and the coupled approach is found to be $\pm 10\,\%$ in the channel and $\pm 50\,\%$ in the backward-facing step, respectively. The viscosity and the elasticity tensor show both significant flow induced anisotropies as well as a strong dependence on closure and coupling.

title: DNS of Turbulent Heat Transfer in Impinging Jets at Different Reynolds and Prandtl Numbers

description: The heat transfer between an impinging circular jet and a flat plate is studied by means of direct numerical simulations for different Prandtl numbers of the fluid. The thermal field is resolved for $Pr=1$, $0.72$, $0.025$, and $0.01$. The flow is incompressible and the temperature is treated as a passive scalar field. The jet originates from a fully developed turbulent pipe flow and impinges perpendicularly on a smooth solid heated plate placed at two pipe diameters distance from the jet exit section. The values of Reynolds numbers based on the pipe diameter and bulk mean velocity in the pipe are set to $Re=5300$ and $Re=10000$. Inflow boundary conditions are enforced using a precursor simulation. Heat transfer at the wall is addressed through the Nusselt number distribution and main flow field statistics. At fixed Reynolds number it is shown that the Prandtl number influences the intensity of the Nusselt number at a given radial location, and that the Nusselt number distribution along the plate exhibit similar features at different Prandtl numbers. The characteristic secondary peak in the Nusselt number distribution is found for both Reynolds numbers for $Pr=0.025$ and $Pr=0.01$. All the simulations presented in this study were performed with the high order spectral element code Nek5000.
description: Data contain mean flow field statistics along the impingement wall of a turbulent impinging jet at Re=5300 and Re=10000. Data are separated in directories for each Reynolds number case. For each case, mean flow statistics of the precursor pipe flow simulation are also reported. Data are stored as csv ascii files and information about the columns are found directly in the files.
