Circulation Flow of Polyacrylamide Aqueous Solution between Coaxial Cylinders with Smooth Surfaces
A mixer with coaxial arrangement of inner and outer circular cylinders with smooth surfaces is considered. During the mixer operation, a circulating flow is formed between the cylinders with the same conditions of motion along the entire length of the annular gap. The smooth surfaces of the inner and outer vertical cylinders reduce the possibility of the polymer solution destruction as an agent for reducing hydraulic resistance due to the high speed of rotation of the inner cylinder and/or the outer cylinder.
