A Settling truncated cylinder in an incompressible viscous Newtonian Fluid
A truncated cylinder sediments in a narrow vertical channel with rectangular cross
section containing 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 truncated cylinder.
- The radius is 0.1 and the length of the truncated cylinder 0.4 in the x directions.
- The density of ellipsoid = 1.1
- The density of fluid = 1
- The viscosity = 0.01
- The mesh size for the velocity field = 1/112
- The mesh size for the pressure = 1/56
- The time step=0.001
- The averaged speed is 2.255 for 6 < t < 8.
- The averaged particle Reynolds number is 90.2 based on
the length of the longest axis (which is 0.4) for 6 < t < 8.
- The mass center moves back the equilibrium position, the centeral axis.
