Interaction of 68 red blood cells behind a moving interface in a microchannel

Interaction of 68 red blood cells behind a moving interface in a microchannel:

The length of the channel is 160 microns and its height is 20 microns.
An interface is moving to the right with a constant speed U=4cm/sec.
The diameter of cells is 7.65 microns and the thickness of cells is 1.986 microns.
The hematocrit (Hct) is 25.175%.
The density of fluid is 1 and the viscosity of the fluid is 0.012.
The mesh size for the velocity field is 10/64 micron.
The mesh size for the pressure is 10/32 micron.
The time step is 0.00001 mini second.

The lateral migration of cells is caused by the deformability and the parabolic profile of Poiseuille flow. These cells in the central region move faster than the speed of the interface and finally they form slug behind the moving interface.
