Caption
The movie shows a fluid in a rigid pipe which is connected to a hose of rubber-like material. A piston moves towards the left through the pipe thereby pushing the fluid out of the hose. Gravity is accelerating the fluid downwards. The faster the piston moves the more the fluid streams towards the left instead of downwards.
Further information
The piston velocities are 0.2 m/s, 0.6 m/s and 1.8 m/s, respectively. In the case of the highest piston velocity, the hose bulges due to the pressure. The results are obtained from co-simulations using the smoothed particle hydrodynamics (SPH) software SimPARTIX for the fluid and the finite element method (FEM) solver Abaqus for the hyperelastic hose. The coupling between the two codes is realized using the co-simulation interface MpCCI.
