摘要：Peristaltic flow of a Prandtl fluid model in an endoscope is analyzed. The flow is modelled in both fixed and wave frame of references. The peristaltic wave move with the speed c. We have used regular perturbation method for the solutions of velocity profile. Expression of pressure gradient and frictional forces is quite complicated, therefore to plot the pressure rise and frictional forces, numerical integration have been used. The effects of various emerging parameters have been discussed for pressure rise, friction forces, pressure gradient and streamlines.
