چکیده
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 and outer tubes and shear stress are obtained in the physical domain. Effect of the non-dimensional wave amplitude, the rotation, the ratio of relaxation to retardation time, the radius ratio and the nondimensional volume flow is analyzed theoretically and computed numerically. Comparison is made with the results obtained in the presence of rotation and an endoscope.
