Viscous flow between two sinusoidally deforming curved concentric tubes: advances in endoscopy

Abstract Viscous flow between two sinusoidally deforming curved concentric tubes is mathematically investigated for the first time. Exact solutions are computed to analyse these and graphical outcomes included a thorough analysis of solutions. The present article has prime applications in endoscopy as novel peristaltic endoscope introduced time sinusoidal tube. This nature outer tube with flexible placed inside it covers topic practical like human organs having shapes maintenance complex machineries that involve curve structures. usage makes process catheterization more comfortable.
