Submarine:
In this simulation the incompressible flow about a submarine is computed together with the free surface motion. The free surface and the surface mesh used for the computation are shown below.
Ship:
In this simulation the incompressible flow about a ship is computed together with the free surface motion. The free surface and the pressure on the surface is shown here.
Armada of Ships:
In this simulation the incompressible flow around a group of ships is computed together with the free surface motion. The mesh consisted of approximately 4.2 Million tetrahedra, and was run in parallel on an SGI Origin 2000 using 8 processors. The free surface and a more appealing view of the surface is shown here.
Fleet of LNG Carriers:
In this simulation six unteethered LNG carriers are being subjected to an incoming wavefield. Each ship is treated as a rigid body that moves according to the hydrodynamic forces. The mesh consisted of approximately 10 Million tetrahedra, and was run in parallel on an SGI Altix using 6 processors.
The free surface is shown below:
Water Mixer:
In this simulation two tubes carrying water merge in a typical mixer geometry, producing a highly transient flowfield. One of the aims of this simulation was to ascertain that the flow in the downward tube does not `clog’, i.e. that there is always a continuous tube of air between the bottom an the top. The mesh consisted of approximately 4.2 Million tetrahedra, and was run in parallel on a workstation with 32 cores. The free surface is shown below.
The left shows a sideview, while the right shows the view from above. One can see that the flow in the downward tube does not `clog’.
