Abstract
The suspension which disperses solid particle changed reological characteristic substantially. Flow characteristic in a gap of hemisphere concentric spheres are studies for viscoelastic liquid contain fiber on suspensions. Rheological behavior of the suspension was studied prior to the flow situation, indicating shear thinning as well as viscoelastic character depending upon the concentration of the fibers. The flow field was observed to be the simple Couette flow in the gap space, but shown the offset from the simple Couette flow as the rotational Reynolds number is increased. It was found that the dependence of the gap width is substantial and Tayler- Gertrudis vortex was controlled by glass fiber.
