Turbulence statistics for an unsteady lock-exchange gravity current during the slumping phase.

Dataset of a lock-exchange gravity current propagating over a mild slope for the computation of turbulence statistics. Data available at t =12.5 s after start of the computation (t_adim = 29.1). The data are saved in the range -0.58 m &lt; x &lt; 2.895 m in the x-direction which encompasses the whole length of the current at this time step. <br> . List of files: - data_t291_vtk.tar.gz -&gt; Contains the 200 simulation results at t_adim = 29.1 used for the statistics calculation. The data are in dimensional form - fields_turbulence_statistics_ensembleAveraging_t29.1 -&gt; Corresponding ensemble- and spanwise-averaged statistics <br> . Scaling quantities for non-dimensionalisation: - Velocity: u_b = 0.349 m/s - Length: H/2 = 0.15 m - Time: t₀ = (H/2)/u_b = 0.43 s <br> . Initial computational domain size: - Lock length: L_x.lock = 0.58 m - Channel length: L_x,channel = 5 m - Domain height: H = 0.3 m - Domain width: L_z = 0.4 m - Inclination: tan(a) = 2% <br> .
