What is it about?
The material in liquid state is injected through a nozzle and solidifies upon contact with a copper rotating wheel. In this work, we intend to find, employing a computer simulation with OpenFOAM®, a thermal profile of the material from its ejection through the nozzle to the conformation of the ribbon itself. A two-phase model of the Volume of Fluids (VOF) type is used. Although neither of the two fluids (molten metal and air) can be considered compressible for working pressures, a resolution method of incompressible nature is used.

Why is it important?
After the introduction of the thermal and viscous model as the first simulation experiment in OpenFOAM®, temperature, and viscosity values can be seen in accordance with those obtained by other authors.
Perspectives
The polynomial proposed by the authors of this work presents discrepancies concerning the Vogel-Fulcher-Tammann model in the range from 887ºC to 1400ºC. These could be eliminated if a modification of the solver source code were introduced into the equation proposed by Vogel-Fulcher-Tammann, which will be treated in future work.
