Pressure flow of the non-Newtonian fluid in an eccentric tube with a rotating inner cylinder. Part 2: Experiments.

Flow of Newtonian and non-Newtonian fluids in a concentric annulus with a rotating inner cylinder

We examine the characteristics of helical flow in a concentric annulus with radii ratios of 0.52 and 0.9, whose outer cylinder is stationary and inner cylinder is rotating. Pressure losses and skin friction coefficients are measured for fully developed flows of water and a 0.4% aqueous solution of sodium carboxymethyl cellulose (CMC), when the inner cylinder rotates at the speed of 0~62.82 rad/...

Non-newtonian Behavior of a Rotating-cylinder Induced Flow

As a cylinder spins in an infinite media, viscous shear forces induce fluid motion and circular streamlines are generated. For Newtonian fluids, a simple analytical solution is possible and widely known. The hydrodynamics of nonNewtonian fluids, however, can be quite complex under such conditions. This paper investigates the behavior of a wide range of non-Newtonian fluids in the infinite cylin...

Some Solutions for Rotating Flow of a Non-Newtonian Fluid

This article considers the rotating flow of a second grade fluid on an infinite plate in the (x, y) plane which moves in the negative direction. The governing time dependent equations in a rotating frame are solved using Laplace transform method. The expressions for the velocity profiles, drag and lateral stress on the plate are obtained. The influence of physical parameters is discussed throug...

Jeffery Hamel Flow of a non-Newtonian Fluid

This paper presents the Jeffery Hamel flow of a non-Newtonian fluid namely Casson fluid. Suitable similarity transform is applied to reduce governing nonlinear partial differential equations to a much simpler ordinary differential equation. Variation of Parameters Method (VPM) is then employed to solve resulting equation. Same problem is solved numerical by using Runge-Kutta order 4 method. A c...
