Abstract: The continuum theory of blood flow developed by Kline and Allen is used to determine two constitutive parameters of blood, the vortex viscosity and the volume averaged radius of gyration, under oscillatory flow conditions at constant flow amplitudes. For a wide range of hematocrits, suspending medium viscosities, and tube sizes. these parameters were found to be frequency invariant.
