Finite Element Method - Application using Fastflo
Water flowing down a slide
Salty water (light green) of density 1.02 is released from a cavity at
the top of a 45 degree slope. It sinks down through water of density 1.0
(red) until it reaches denser salty liquid (1.04, blue). It then travels
along the top of the denser fluid, setting up a sloshing motion, which is
fairly soon damped.
The Grashof number is 106, and the Schmidt (Prandtl) number
is 400. The mesh consisted of six-noded triangles, and had 19,676 nodes.
An operator splitting algorithm was used, programmed in Fastflo.
