Dataset for Turbulent Flow in Binary Barchan Interaction: PIV_Dunes_in_Interaction

The following folders contain data obtained from two-dimensional Particle Image Velocimetry (2D-PIV) experiments for each region where measurements were conducted. Due to the domain size and experimental constraints, the domain containing the barchan dune interacting with a turbulent water flow was divided into three sections (parts). Along the folders, these portions of the domain are referred to as part_1, part_2, and part_3. Cross-correlated PIV data, in vc.7 format, obtained from the commercial software DaVis, are made available. However, due to size restrictions of this data repository, only 10% of the total of 2,000 temporal velocity fields are included. Post-processed data, saved as Matlab matrices, are also made available, corresponding to the total of the 2,000 temporal velocity fields. Additionally, Matlab codes are provided to generate the matrices from the data on DaVis and to plot pertinent results. Note that this folder contains only data from experiments on interacting dunes. In each subfolder is provided an explanation of its contents.
