Title: Impact of Coagulation on Peristaltic motion of Particle-fluid suspension through an annulus


Peristalsis is a mechanism of fluid motion that arises when smooth muscles in a living body contract and expand along the length of channel or tube. It is a hereditary property in various biological systems which comprises of smooth muscles and movement of different kinds of biological fluids (i.e. blood etc.) by its propulsive action. This mechanism can also be noticed in cilia motion, movement of urine (kidney to bladder), Chyme movement, vasomotion of tiny blood vessels, a motion of the intra-uterine fluid and in different kinds of glandular ducts. Peristaltic phenomena have been oppressed in various industrial applications. Examples include blood pumps, transport of sanitary and corrosive fluid etc. Particle-fluid is very much pervasive in nature and technology. The particle-fluid suspension can also be analyzed in various problems arises in biological and physical science. An important property of particlefluid that separates them from the rigid particles is their deformation during motion and mobile surface. Particles in fluid reveal many shapes, even their dependence on the magnitude and different forces that exist in continues phase. Moreover, the shape of particles in fluid change with their position and time during its movement. A counter example of a particle-fluid collision at mesoscopic level is the motion of Red blood cells (RBCs). The attitude of Red blood cells plays a critical role in different pathological and physiological mechanism at microcirculation level. For instance, in thrombogenesis, the rotation and transverse motion of Red blood cells in a shear flow play a significant role. The present study deals with the effects of coagulation (clot blood) on peristaltically induced motion of particle-fluid suspension towards a non-uniform porous annulus has been analyzed. The effects of an endoscope, constant magnetic and Hall Effect are also taken into account in our present study. The governing flow problem consists of continuity and momentum equation which are simplified for fluid phase and particle phase by taking the assumption of long wavelength and creeping flow regime. The Prandtl fluid model is considered for the governing flow problem. We considered a small tube having a sinusoidal peristaltic wave traveling down towards its wall having constant velocity and a clot model inside it. The solutions for fluid phase and particle phase are obtained analytically using perturbation method. The physical effect of all the involve parameters are such as a height of the clot, particle volume fraction C , fluid parameter,Hartmann number M , Hall parameter m , porosity parameter k are discussed for friction forces and pressure rise, respectively.
