The motion of a neutrally buoyant prolate in a tube Poiseuille flow
The motion of a neutrally buoyant prolate in a pressure driven tube Poiseuille flow for 0 < t < 15:
The long axis is initially perpendicular to the central axis of the tube.
- The flow is periodic in the horizontal direction.
- The length of the cylinder is 2 and its radius is R=0.5.
- The dimension of computational domain = (0,1+4h)x(0,2)X(0,1+4h).
- The initial velocity field is a fully developed tube Poiseuille flow with maximal speed
of 10.
- Three semi-axes of the prolate are 0.065, 0.065, 0.195.
- The density of tha prolate is 1.
- The density of fluid is 1.
- The viscosity is 0.1
- The pressure drop is 16 per unit length.
- The mesh size for the velocity field is h=1/80.
- The mesh size for the pressure is 1/40.
- The time step=0.001.
- The distance from the mass center to the central axis is 0.2597 (0.5194R).
- The averaged translation speed is 6.732 for 390 < t < 400.
- The averaged particle Reynolds number 26.23 for 390 < t < 400.
