Turbulence & Rheology, Dr. D. Penney
FACTORS RESPONSIBLE FOR FAHRAEUS-LINDQVIST (SIGMA)
EFFECT (in tubes where R = 1000 ----> 7 um).
Fahraeus Effect (dynamic hematocrit falls below bulk hematocrit in tubes to D = 15 um)
higher v of erythrocytes than plasma
plasma skimming (RBC screening) present below D = 30 um; less at high Pp and Sw.
relatively larger slippage layer in smaller bore tubes
high shear rate
increased RBC deformation
"tank treading" by erythrocytes multifile vs. single file flow, unknown? (D = 15 -7 um)
