Turbulence & Rheology, Dr. D. Penney
FACTORS CAUSING FLOW NOT TO BE INITIALLY PROPORTIONAL TO DRIVING PRESSURE
(Eta decreases with increases in Pp and shear rate at small values of Pp and shear rate):
Axial flow, thus cell free (slippage) layer within 4 um of the wall (Einstein)
RBC orientation relative to wall and other erythrocytes
Rouleaux break - up
Note: Erythrocytes stand away from vessel wall, according to the Einstein eq.
