Exact peristaltic flow in tubes with an endoscope

摘要

Peristaltic flow of a Jeffrey fluid through the gap between concentric uniform tubes has been investigated with particular reference to an endoscope effects. The velocity components and axial pressure gradient are obtained analytically. Numerical integration is performed in order to analyze the pressure rise and frictional forces on the inner and outer tubes. The obtained results are compared with the earlier studies existing in the literature.
