Abstract
The peristaltic flow of a Prandtl fluid model in an endoscope is analyzed. The flow is modeled in both fixed and wave frame references. We applied the regular perturbation method to solution of the velocity profile. Since it is quite complicated to express pressure rise and frictional forces, numerical integration was used to plot the pressure rise and frictional forces. The effects of various emerging parameters are discussed in respect of pressure rise, friction forces; pressure gradient and streamlines.
