An ellipsoid sediments in a 2D-like channel filled with an incompressible viscous fluid:
- The dimension of computational domain = (0,1)x(0,0.25)x(0,4) initially,
then it moves vertically with the center of the ellipsoid
- Three semi-axes are 0.1, 0.1 and 0.2.
- The density of ellipsoid = 1.1
- The density of fluid = 1
- The viscosity = 0.01
- The mesh size for the velocity field = 1/160
- The mesh size for the pressure = 1/80
- The time step=0.0005
- The averaged speed is 2.6 for 3 < t < 4.
- The averaged particle Reynolds number is 104 based on
the length of the longest axis (which is 0.4) for 3 < t < 4.
- The mass center moves back the equilibrium position, the centeral axis.
