TITLE : Water pouring into a bund

PHOENICS Version : 3.3.1

PHYSICAL SITUATION :

• Three-Dimensional Transient Free Surface Flow of Water in Air.

• The task is to simulate the water pouring into a bund through the bottom slot at the side wall. The opposite side wall has an opening through which the water leaks out of the bund. Internal obstacle is located on the water path.

• Water starts to propagate into the bund along the horizontal floor until it encounters the internal beam. It re-directs the water stream until it finally reaches the leak opening over-flowing the obstacle.

NUMERICAL DETAILS :

• Cartesian computational uniform grid.
• 100 time steps of 0.02 time units covering a total period of 2 time units.
• The effects of wall friction and turbulence are neglected.
• The free surface is modelled by use of SEM, Scalar Equation Method .

PICTURES are as follows:

• Geometry of the bund
• Free surface at the quarter of simulation time
• Free surface at the middle of simulation time
• Free surface at the end of simulation
• Velocity vectors and density distribution at the end of simulation

THE IMPLEMENTATION

All model settings have been made in VR-Editor of PHOENICS 3.3.1.
