Abstract: |
Simulation results of the Collision of two droplets of the fully wetting immiscible liquids SOM5 (Silicon Oil M5) and G50 (Glycerol-Water solution 50%) produced with the in-house of the Institute of Aerospace Thermodynamics code FS3D for the final report of the SFB-TRR75. <br> For liquid properties see <a href="https://doi.org/10.1017/jfm.2012.94">doi: 10.1017/jfm.2012.94</a>.<br><br> Methods used: <ul> <li>Volume of Fluid Method</li> <li>Three-material PLIC reconstruction (compare: <a href="https://arxiv.org/abs/2105.08972">arXiv: 2105.08972</a> and <a href="https://arxiv.org/abs/2104.11108">arXiv: 2104.11108</a>)</li> <li>static contact angle reconstruction (compare: <a href="https://arxiv.org/abs/2104.11108">arXiv: 2104.11108</a>)</li> <li>CSS surface force model for three immiscible components with a film stabilisation is utilised (compare: <a href="https://arxiv.org/abs/2104.11108">arXiv: 2104.11108</a>)</li> </ul> |

Kind of Data: |
HDF5 simulation results |
|
Notes: |
The HDF5 Data can be loaded with Paraview, by opening fs3d.xmf which contains the data structure.<br><br> The VISUS PLIC Plugin <a href="https://github.com/UniStuttgart-VISUS/tpf">https://github.com/UniStuttgart-VISUS/tpf</a> can be used for reproducing the pictures from the final report. <br><br> Each tar.gz file contains the following files: <ul> <li><b>fs3d.xmf</b> Timeline of the hdf files, can be loaded to paraview with Standard Paraview Readers (tested for Paraview 5.8.1), contains the data structure, i.e. the timeline associated to the pictures</li> <li><b>fun3XXXX.hdf</b> Volume fraction of first liquid phase (G50) in picture XXXX</li> <li><b>funsXXXX.hdf</b> Volume fractions of second liquid phase (SOM5) in picture XXXX</li> <li><b>n3phXXXX.hdf</b> Interface orientation of second liquid phase in picture XXXX</li> <li><b>netz_xyz.hdf</b> Grid corner points (i.e. for Paraview)</li> <li><b>initialization_data.txt</b> Information on the initialized droplets (Radius, Velocity, Properties, Domain). Here, <code>f</code> always indicates the second liquid, <code>f3</code> the first liquid, <code>fc</code> the gaseous continuous phase (like in FS3D Software). G50 is associated with <code>liquid 1</code> (f3) and SOM5 with <code>liquid 2</code> (f). For an overview, the content of these files is also given below. </li></ul><br> <u>Coalescence Case from final report of SFB-TRR75 Project A7</u><br> Dimensions in all directions: -0.04 ... 0.04 cm <br> Points per Direction: 128<br> Initialized Center of liquid 2 (f) : [0.008798572807385, 0.011201427192615,0.0] cm<br> Initialized Radius of liquid 2 (f): 0.0097265 cm<br> Initialized Velocity of liquid 2 (f) in x as well as y direction : -69.8267946421716 cm/s<br> Initialized Center of liquid 1 (f3) : [-0.01, -0.01,0.0] cm<br> Initialized Radius of liquid 1 (f3) : 0.0093428 cm<br> Initialized Velocity of liquid 1 (f3) in x as well as y direction : 69.8267946421716 cm/s<br><br> Densities: <ul> <li>of liquid 2: rhof=0.9134 g/cm^3,</li> <li>of liquid 1: rhof3=1.126 g/cm^3, </li> <li>of the gas: rhofc=0.00119 g/cm^3</li></ul> Viscosities:<ul> <li>of liquid 2: muef=0.0457 g/(cm s), </li> <li>of liquid 1: muef3=0.06 g/(cm s), </li> <li>of the gas: muefc=0.0001824 g/(cm s)</li></ul> Interfacial tensions: <ul> <li>of the liquid 2-gas interface: sigma=19.5 g/s^2, </li> <li>of the liquid 1-gas interface: sigma_f3=68.6 g/s^2, </li> <li>of the liquid 1-liquid 2 interface: sigma_f3f= 34.3 g/s^2</li></ul> Static imposed contact angle: 1e-12°<br><br> <u>Separation Case from final report of SFB-TRR75 Project A7</u><br> Dimensions in x and y directions: -0.05 ... 0.07 cm <br> Dimension in z direction: -0.04 ... 0.04 cm <br> Points per x/y Direction: 192<br> Points per z Direction: 128<br> Initialized Center of liquid 2 (f): [0.009815261989454, 0.010184738010546,0.0] cm<br> Initialized Radius of liquid 2 (f): 0.0097225 cm<br> Initialized Velocity of liquid 2 (f) in x as well as y direction : -131.20366324916 cm/s<br> Initialized Center of liquid 1 (f3): [-0.01, -0.01, 0.0] cm<br> Initialized Radius of liquid 1 (f3): 0.0093428 cm<br> Initialized Velocity of liquid 1 (f3) in x as well as y direction : 131.20366324916 cm/s<br><br> Densities:<ul> <li>of liquid 2: rhof=0.9134 g/cm^3, </li> <li>of liquid 1: rhof3=1.126 g/cm^3, </li> <li>of the gas: rhofc=0.00119 g/cm^3</li></ul> Viscosities: <ul> <li>of liquid 2: muef=0.0457 g/(cm s), </li> <li>of liquid 1: muef3=0.06 g/(cm s), </li> <li>of the gas: muefc=0.0001824 g/(cm s)</li></ul> Interfacial tensions: <ul> <li>of the liquid 2-gas interface: sigma=19.5 g/s^2, </li> <li>of the liquid 2-gas interface: sigma_sg=68.6 g/s^2, </li> <li>of the liquid 2-gas interface: sigma_sl= 34.3 g/s^2</li></ul> Static imposed contact angle: 1e-12° |
