For apparent turbulence in blood, it is usually assumed that eddies cascade down to dissipative length scales on the order of tens of microns.  In "Rethinking turbulence in blood", Luca Antiga and I suggest that this cascade may be interrupted by the presence of red blood cells (RBC) at physiological concentrations, and show how this might give rise to strong viscous shear stresses between cells -- stresses that may be on the order of the "fictional" Reynolds stresses normally invoked to rationalize the behaviour of RBC in turbulent flows.
