Experimental data for: Influence of wall material and vacuum conditions on lunar regolith flow stability in a rotating drum

This repository contains experimental data and analysis results for the study on regolith-wall interactions under vacuum conditions. The data is organized to support the findings of the associated manuscript on lunar regolith flow stability. Materials studied: PETG PETG-R (Roughened using fuzzy-skin texturing) PTFE Aluminum Copper Files: materials.zip: Contains all experimental media. This archive is organized by wall material, environment (air/vacuum), rotational speed (2, 6, 12 RPM), and individual experimental trials. It includes both raw .MOV video recordings and the processed video frames used for boundary detection and segmentation. metrics_frame_level.csv: Comprehensive CSV file containing the frame-by-frame measurement results for all experiments, including calculated surface angles and stability metrics.
