Development of a Peristaltic Endoscope
نویسندگان
چکیده
A device that could locomote through curving and tortuous spaces would find many applications in medicine and in industry. Invertebrates such as earthworms and leeches can solve this problem using peristaltic locomotion. We describe a device consisting of three braided pneumatic actuators in series that can successfully locomote peristaltically. The device can locomote forwards and backwards in elevated and curving tubes, and with a plastic sheath around it.

Effects of an endoscope and rotation on peristaltic flow in a tube with long wavelength
The objective of this project is to study examines the problem of peristaltic flow in a tube with an endoscope subjected to rotation. The effect of an endoscope and rotation of the peristaltic flow of a Jeffrey fluid through the cylindrical cavity between concentric tubes is investigated. The analytical expressions for the pressure gradient, velocity, pressure rise, friction force on the inner ...
متن کاملMagnetic Field and Endoscope Influences on Peristaltic Transport: an Exact Solution
The effect of magnetic field on peristaltic flow through the gap between uniform tubes is studied under the assumption of long wavelength at low Reynolds number. The inner tube is rigid and the outer tube has a sinusoidal wave travelling down its wall. The flow is investigated in a wave frame of reference moving with the velocity of the wave. The analytical solution for velocities and pressure ...

In the present article, we have studied the effects of heat transfer on a peristaltic flow of a magnetohydrodynamic (MHD) Newtonian fluid in a porous concentric horizontal tube (an application of an endoscope). The problem under consideration is formulated under the assumptions of long wavelength and neglecting the wave number. A closed form of Adomian solutions and numerical solutions are pres...
