Description

Supplementary material to the manuscript: R. Saha, M. Kumar, S. Tonini, G.E. Cossali, B. Weigand, "Local heat flux distribution at the solid-liquid interface during droplet impact and spreading at a hot substrate", which has been accepted in Physics of Fluids and will be published in an upcoming issue.

A water droplet of size 2.3 mm with a Weber number of We = 20 (Reynolds number of Re = 1817) impacts perpendicularly onto a hot silicon hydrophobic substrate is simulated. The DNS simulation is performed using the multiphase in-house solver FS3D at the Institute of Aerospace Thermodynamics, University of Stuttgart.

The dataset contains the raw simulation data (hdf5-files) of certain timesteps as well as raw data for dynamic wetting. In particular, the data set contains (1) the converged numerical solution and (2) the mesh convergence data for dynamic wetting.

(1) The simulation data contains the solid-liquid-gas volume fractions, flow field, temperature distribution, and pressure field. To visualize in ParaView, please open the file fs3d.xmf, and it will automatically load all the scalar and vector fields. The simulation was conducted till 5ms.

(2) The simulation data contains the raw data for different mesh resolutions, i.e., 64^3, 128^3, 256^3, 512^3 and 768^3. The first column shows the physical time (ms), and the last column shows the wetting area (cm^2). Please note that the simulation is conducted for 1/4th of the process. The columns in between are other numerical parameters, which are not relevant for dynamic wetting.

We appreciate the financial support for this work from the Deutsche Forschungsgemeinschaft (DFG) within the framework of the International Research Training Group “Droplet Interaction Technologies” (GRK 2160/2: DROPIT) under project number 270852890 and under the framework of the SimTech project number EXC2075/2-390740016. Furthermore, we would like to thank the High-Performance Computing Center Stuttgart (HLRS) for providing computation time on the HPE Apollo (Hawk) and HPE Cray EX4000 (Hunter) platforms under grant number FS3D/11142.
