In the present study, the power consumption in a stirred vessel by two-blade impeller has been investigated. 3D finite volume based computational fluid dynamics (CFD) simulations have been carried out. The tank used has a cylindrical shape with a flat bottom. The liquid height was kept equal to the vessel diameter. Study has been restricted to the laminar regime with Newtonian and shear thinning fluids,...
The present paper treats the agitation of shear thinning fluids in a cylindrical unbaffled vessel with a flat-bottom. Two kinds of impellers have been used: simple and double helical ribbons. This work is achieved with the help of CFD package (CFX-12.0), which is based on the finite volume method to solve the continuity and momentum equations. The effect of impeller rotational speed, fluid rheology,...
