| dc.description | This dataset accompanies the article "Insights into the Dynamics of Crown Splash Using a Phase-Field Interface-Capturing Method" by Bagheri et al. It provides both experimental and numerical data characterising the impact of a single liquid drop onto a stationary thin liquid film, for two sub-millimetre film thicknesses (h = 0.4 mm and h = 0.5 mm), and is intended to serve as a quantitative benchmark for the validation of numerical methods for two-phase flow. The quantitative data are organised in a single Excel workbook (CrownSplash_Benchmark_Data.xlsx) containing six worksheets. Two worksheets (one per film thickness) report time-resolved experimental measurements and corresponding numerical-simulation results for the four crown geometric parameters used in the paper - the diameter at the base (D_Base), at the mid-height (D_Mid), and at the rim (D_Rim), and the crown height (H_Rim) - together with the experimental standard deviation obtained from 10-14 repetitions of each case. Two further worksheets report the time-resolved residual film thickness obtained from the numerical simulations for both cases. The remaining two worksheets report the time-resolved liquid-sheet thickness extracted from the simulations at multiple vertical positions across the crown wall, a quantity that is essentially inaccessible experimentally. Five supplementary videos are also included: two standalone high-speed experimental recordings of the drop impact and crown evolution (one per film thickness), two side-by-side comparisons of the experimental recordings and the phase-field simulations (one per film thickness), and one visualisation of the simulated velocity field within and around the developing crown for the h = 0.4 mm case. The direct numerical simulations were carried out using the phase-field (Cahn–Hilliard–Navier–Stokes) method in OpenFOAM (FOAM-extend), combined with dynamic load-balanced adaptive mesh refinement. Full methodological details are provided in the accompanying article, and a README file included in the deposit documents each worksheet column by column. | |
