| Summary | 0004237: liquid columns with different viscosities falling down at different speeds. | ||||
| Description | I am in the course of simulating a non-Newtonian slurry with incompressbleVoF. When trying to reproduce an experiment where the slurry falls from a height of 0.5m down on a flat plate I came across the result that the slurry takes much longer to hit the flat plate on the bottom than I expected it to (I would expect a time of roughly 0.32s - in the simulation it took almost 2 seconds) So I had a look into an easy example: A column of water at regular conditions (1) and with a very high viscosity (2) but besides that with no differences (see attached examples). In the one case it takes ~ 0.3 sec to reach the bottom, in the other case it takes ~2.7 s While the viscosity surely has an impact on the deformation and splashing behaviour of the column, I would expect the column to fall down in a comparable time. | ||||
