Dataset for "Roughness spacing controls nonlinear flow and transition in three-dimensional rough fractures"

This dataset contains the processed numerical results supporting the manuscript entitled "Roughness spacing controls nonlinear flow and transition in three-dimensional rough fractures." The dataset consists of four Excel workbooks corresponding to four roughness spacing conditions (lc = 1, 2, 4, and 8). Each workbook contains the pressure gradient, average flow velocity, and Reynolds number for 10 stochastic fracture realizations under multiple loading conditions. These data were used to determine the Forchheimer coefficients, hydraulic aperture, effective aperture, and nonlinear flow characteristics presented in the manuscript. All figures and tables in the paper can be reproduced from the data provided.
