Static Mixers

Blending in a static mixer can be directly related to a series of  dimensionless numbers that can be used to describe blending characteristics.

blending

Where Re = Reynolds Number

m = Absolute viscosity

m 1/m 2 = Viscosity ratio of unmixed streams

r 1/r 2 = Density ratio of unmixed streams

V1/V2= Volumetric ratio of unmixed streams

n = Shear rate

n = Number of elements

L/D = Element length to diameter ratio

Inj. = Injection method of additive stream
