Replication Data for: "Vortex structures under dimples and scars in turbulent free-surface flows" (PART 2/4)

DOI

This data archive (along with parts 1, 3 and 4) contains simulation data for direct numerical simulations of isotropic turbulence interacting with a free surface, for different Reynolds numbers and Weber numbers. The data is generated by computing time evolution of the incompressible Navier-Stokes equations and continuity equation on a three-dimensional domain, which is periodic in horizontal directions, restricted from above by a deformable free surface (resolved by the kinematic and dynamic boundary conditions on a surface-adhering grid) and below by a free-slip boundary. Turbulence is generated by linear forcing in the centre of the domain.

For more detail on the simulations, parameters and flow problem, see the research article "Vortex structures under dimples and scars in turbulent free-surface flows", by Aarnes, JR, Babiker, O, Xuan, A, Shen, Lian, and Ellingsen, SA, in the Journal of Fluid Mechanics (2025).

The data archive is split over four different repositories (case details in Aarnes et al., 2025).): Part 1: Data for case 1, Re = 2500, We = infinity. (doi.org/10.18710/XQ81WH) Part 2: Data for case 2, Re = 2500, We = 20. (doi.org/10.18710/MBK9JF) Part 3: Data for case 3, Re = 2500, We = 10. (doi.org/10.18710/PN7DZA) Part 4: Data for cases 4-6, Re = 1000, We = infinity, 20, 10. (doi.org/10.18710/UAT043)

Each archive also contains the same readme file with instruction on how to get started and a data loader script which can read the binary files which the .tar-files contain. Due to storage limitations, only data for the upper part of the flow is included in this data archive. The thickness of the upper part is two times the viscous boundary layer. Moreover, the data is limited to approximately half of each time series, also to limit the storage requirement.
