Fluid transport with suspended particles by means of dilating peristaltic waves

Abstract: In the present study, transport of a Newtonian fluid containing uniformly distributed tiny particles moving in a cylindrical tube is investigated when the peristaltic wave amplitude dilates exponentially. Long wavelength approximation is used to get rid of non-linear inertia terms. It is observed that dilation of wave-amplitude during propagation enhances pressure but reduces it with rising concentration of particulate suspension. Pressure rises with the amplitude dilation parameter in case solid particles are… Show more

“…Their assumption of waves with increasing amplitude, based on anatomical data produced by Xia et al [7], endorsed the experimental outcome of Kahrilas et al [8] of higher pressure in the distal part of the oesophagus required for swallowing of food boluses which become gradually globular while traversing the journey from the phyrangeal to the cardiac sphincter. Following this, several modifications to previous investigations on non-Newtonian fluids were reported ( [9][10][11][12]).…”
