A hundred blood cells move in a microchannel

100 red blood cells in a microchannel:

The length of the channel is 100 microns and its height is 50 microns.
The flow is periodic in the horizontal direction.
The averaged speed is 1.666 cm/sec when there is no cells.
The diameter of cells = 7.65 microns and the thickness of cells = 1.986 microns.
The hematocrit (Hct) is 23.69%.
The density of fluid is 1 and the viscosity of the fluid is 0.012.
The mesh size for the velocity field is 1/32.
The mesh size for the pressure = 1/16.
The time step=0.00001 ms.
The averaged speed at t=60 ms in the channel is 1.068 cm/sec (Re=0.445).
The averaged shear rate on the wall at t= 60 ms is 1996/sec and the capillary number is 1.815.
