Experimental Data of Supercritical Carbon Dioxide (sCO2) Compressor at Various Fluid States - Supplementary Data

<p>This repository contains additional data for the publication "Experimental Data of Supercritical Carbon Dioxide (sCO2) Compressor at Various Fluid States". The data repository contains the entire compressor geometry, including CAD models, and input files suitable for mean-line and grid generation programs. Thus, the experimental results presented and discussed in the paper are exploitable by the scientific community and pave the road for validated analysis and design tools in the context of the sCO2-Joule cycle.</p>
<b>Methods</b>
<p>The data in the folder "CAD-Repository" is derived from the original CAD-model used in the manufacturing process of the entire sCO2-HeRo turbo-alternator-compressor system. Features not related to the flow path, such as screws and shaft-hub-connections, are removed to ease the use of the data. The folder named "CFD-AxSymetric_Repository" contains the axisymmetric contour (meridional contour) as well as the blade contour. This data is extracted directly from the original CAD-model. The geometric data in the folder "Mean-line_Repository" is as well extracted directly from the original CAD-model. The blade angle beta_2, blockage b_1 and b_2 are determined from flow simulations conducted with the CFD solver Ansys CFX. The computational aided design (CAD) software PTC Creo Parametric 4.0 was used throughout the data generation process. In detail, PTC Creo Parametric 4.0 was used to generate the original CAD-model, including all features and used in the manufacturing process of the entire turbo-alternator-compressor system. PTC Creo Parametric 4.0 was used to extract the axisymmetric contour (meridional contour), the blade contour and the characteristic dimensions of the compressor. The figure "CFD-AxSymetric_Repository\ sCO2-HeRo_compressor_figure.emf" was plotted from the data stored in the text files in the folder "CFD-AxSymetric_Repository" with Mathworks MATLAB 2017.</p>
