This repository is primarily focused on presenting research data from the mesh sensitivity analysis conducted on the first stage of a centrifugal compressor impeller. The primary aim is to understand the impact of various mesh configurations on the compressor's overall performance. The dataset highlights the outcomes of the mesh sensitivity analysis, encompassing results for 9 variants of mesh density. Data Overview: Mesh Parameters Description: Detailed information about mesh parameters (17 values) is provided in an Excel file (xlsx format), offering a clear and organized presentation of critical data. Numerical Calculation Results: The repository includes selected results from numerical simulations for nine distinct blade configurations, offering insights into the performance implications of each configuration. Data Specifics: The data vividly demonstrates the results of mesh sensitivity analysis across 9 different mesh density variants. This provides a comprehensive understanding of how variations in mesh density can influence the performance and efficiency of the first stage of a centrifugal compressor. Discipline Focus: The repository is an invaluable asset in the field of Mechanical Engineering, particularly beneficial for those specializing in fluid-flow machinery design.


Steps to reproduce

The data was produced based on calculations prepared using Ansys software, specifically employing the CFX module to conduct these calculations. Points were used to prepare the mesh, and the variants of the mesh were calculated using the CFX solver. Finally, data such as efficiency and power were extracted from the results file to facilitate an easy comparison of parameters.
