The flow feature and local shear rate distribution near the impeller blade in a standard Rushton turbine stirred tank with the aqueous solution of sodium polyacrylate were studied by using particle image velocimetry experiments and computational fluid dynamics simulations. Experimental and simulated results, including average velocity and local shear rate distribution at different rotational speeds,...
The way in which the single phase flow of Newtonian liquids in the vicinity of the impeller in a Rushton turbine stirred tank goes through a laminar‐turbulent transition has been studied in detail experimentally (with Particle Image Velocimetry) as well as computationally. For Reynolds numbers equal to or higher than 6000, the average velocities and velocity fluctuation levels scale well with the...
