Separation of particles of different sizes from non ...

Only in the shear thinning fluid, the separation of large particles from a mixture of particles with different sizes was achieved. This separation has been found to be possible because of the fast migration of non-interacting particles across streamlines and the proper partitioning characteristics at the
