Summary
DescriptionPainting with non-newtonian fluid.jpg |
English: In the picture, a non-newtonian fluid dripping down a flat surface is shown. In non-newtonian fluids, viscosity varies with the stress. This means that the fluid behaves differently in case it is under low stress conditions or high stress conditions. In the picture, a flat surface covered with non-newtonian fluid is oriented vertically, and it is possible to see that the fluid starts dripping down the surface (before taking the picture the flat surface was horizontal, placed on a table). When the surface is vertical the non-newtonian fluid is subjected to the stress due to the gravitational acceleration. Therefore, instead of slipping along the surface, it forms very large drop, that are very dense and almost solid. This creates the great effect that can be seen in the figure.
Italiano: Nell'immagine è possibile notare una superficie verticale da cui cola un fluido non newtoniano. Nei fluidi non newtoniani la viscosità varia con la tensione a cui si sottopone il fluido. Questo significa che il fluido si comporta in modo differente in base alla tensione a cui è sottoposto. Nella figura una superficie ricoperta da un fluido non newtoniano è stata posta verticalmente (prima della fotografia essa era posta orizzontalmente). Il fluido non newtoniano è dunque posto ad una certa tensione dovuta alla forza di gravità ad esso applicata. A causa dell'aumento della tensione esso inizia a comportarsi come un solido e si creano delle grandi gocce di materiale quasi solido. Questo crea lo strano effetto che è possibile vedere nell'immagine. |
