Full TextAbstract
The present study attempted to solve falling cylinder governing equation for power law model fluids and also construct a novel falling cylinder rheometer (F.C.R.) to measure the rheological properties of power law model non-Newtonian fluids. Different falling cylinders with predesigned densities were used to determine the apparent viscosity of Polyvinylalcohol solutions in water with various concentrations. The results indicate that all P.v.a. solutions obey the power law model which power law index as well as consistency index change linearly with concentration. Increasingconcentration of the solution decreases power law index while enhances consistency index and apparent viscosity.
