Numerical Assessment of In-Line Rotor–Stator Mixers in High

Aug 12, 2020  In this article, computational fluid dynamics (CFD) is employed to compare three rotor–stator mixers running in both batch mode and continuous, or inline, modes with a background flow of 0.1 m s −1 (corresponding to a Reynolds number Re of 8000). Since deagglomeration and mixing both depend on the flow conditions around the rotor–stator ...

High Shear Mixer: What Is It? How Does It Work? Types Of

High shear mixers generally have two main parts: the rotor and the stator. This assembly is known as the mixing head or generator. The rotor accelerates the fluid tangentially. The inertia of the fluid, keeps it from flowing together with the rotor. The fluid flows towards the shear gap or the region between the rotor tip and the stator.

CFD analysis of a rotor-stator mixer with viscous fluids

May 01, 2006  The definition of the Reynolds number for a rotor-stator is ambiguous. One possible definition is that for impellers in tanks: (1) Re = ρ ND 2 μ, where ρ is the density of the fluid, N the rotational speed, D the impeller diameter and μ the viscosity. Another possibility is based on the rotor-stator gap width and the tip speed as characteristics dimensions based on
