PULSATILE FLOW OF BLOOD WITH VOLUME FRACTION OF MICRO-ORGANISMS

In this paper the pulsatile flow of blood with volume fraction of microorganisms has been planned to study by assuming blood as couple stress fluid and dusty particles as microorganisms. The velocity expressions for both blood and microorganisms have been obtained in Bessel-Fourier series form. By the proper substitution the velocity expressions for blood can be reduced to pulsatile and steady flow of couple-stress and Newtonian fluid in the presence/absence of microorganisms. Further from the present analysis the expressions for flow rate, apparent viscosity, phase-lag between flow rate and pressure gradient have been derived. The results obtained in this model will be compared with the existing experimental results and theoretical models.
