Multiphase

This analysis type is used to simulate the time-dependent behavior of fluid mixtures, for example air and water. The analysis is carried out using the VoF (Volume of Fluid) method which is a standard approach for the computation of multiphase systems. | Page 43

Water entering and passing a drain in a drainage system

In this project, the fluid flow direction in a rotating system is investigated. This project aims to recreate an experiment that I saw some while ago. This experiment is a container with hoses, that are able to rotate around the centre of the container. The hoses are either pointing out of the centre of rotation or pointing toward  the centre of rotation. Consider the hoses pointing outward, if we rotate the system the water leaves in the opposite direction as the hoses are moving. Counterintuitively, when the hoses point toward the center, the water leaves in the same direction as the hoses are moving. The simulation is a multiphase simulation with a rotating zone.

Full details about the simulation, the experiment and additional information is provided in the comments.
