Numerical Data of the Asymmetric Inner Film Flow during Oblique Droplet Impact onto a Wall Film

<p>Supplementary material to a submitted manuscript [full citation link follows when it is published], referred to as related publication in the following. <br>
Direct Numerical Simulation of an oblique droplet impact onto a thin wall film (Isopropanol, air) performed with the ITLR in-house program package Free Surface 3D (FS3D). The code solves the incompressible Navier-Stokes equations in a one-field formulation with a Volume of Fluid (VoF) approach, see related publication. The simulation was performed in three dimensions (1024*512*512), cropped to 512*103*293.<br>
The y- and z-axes are interchanged compared to the related publication. </p>

<p>The data is saved in hdf5 files. For the here published timestep, there is one file storing the VoF-variable, which is a scalar field with values between 0 and 1 indicating the phases being ambient gas (0) or drop liquid (1), (funs0007.hdf). Additionally, there is another file for storing the velocity vector field (velv0007.hdf). In total, there are 7 different cases (varying impact conditions) published, each for the evaluated timestep of tau=1.5 of the related publication.<br>
The reference impact conditions are, details can be found in the related publication: D=1.5mm, U=2.868m/s, h_f0=0.3mm, alpha=70°, delta=0.2, We=450, Oh=0.014.<br>
1: Reference Case<br>
2: alpha = 60° <br>
3: alpha = 50° <br>
4: We = 0.5*We_ref <br>
5: Oh = 0.3*Oh_ref <br>
6: delta = 2*delta_ref <br>
7: free-slip condition <br>

The simulation was performed as part of the GRK 2160 within the subproject SP-C2.
