The
LINE STATIC MIXER unit is an inline,nomovingpart, continuous
mixing
and
processing unit. 

The
static mixer unit is constructed of a number of short
elements of right and
lefthand
helices. These elements are alternated and oriented so
that each leading
edge
is at 90 to the trailing edge of the one ahead. In general,
the length of the
individual
element is approximately 1.5 diameters. 



At
the leading edge of each element the flow divides and
follows the semicircular
channel
created by the element shape. At each succeeding element
the two flows
are
further divided, resulting in an expon ential progression
of flow division.
The
progression is described by the formula :
S
= 2©ú
where
S is the number of striations produced and n is the number
of elements
in
the unit. After the flow has passed through 20 elements,
over a million
striations(220)
exist.
The
thickness of striations,d,is defined as:
d
= D/2©ú
where
D is the inside diameter of the unit.

Since
the mixer elements are alternately arranged in right twist
and left twist, the
fluid
is inverted in flow direction as it passes through each
element.



The
fluid runs along the twisted surface of element, and moves
continuously in the
position
in the radial direction, flowing from the central part
to the pipe wall side,
and
from the pipe wall to the central part.
