An analytic solution and investigation of character of viscoelastic fluids in double-gap concentric cylinder rheometer
An analytical solution to annular pipe flow of the second order fluid and Maxwell fluid is given using Weber integral transform. The formulae can be used to analyse the flow character of double-gap concentric cylinder rheometer. It is found by computation that when the outer cylinder is in simple periodic motion, there are step junctions along the history curve of Maxwell fluid's velocity and shear stress; when the outer cylinder rotates uniformly, the velocity and shear stress of Maxwell fluid exhibit rhombic wave oscillation.
