static mixer elements located along a longitudinal axis of the
first mixer for mixing the media; and
thereafter passing the media from the first mixer into a
second mixer fluidly coupled to the first mixer and having a
substantially constant, cross-sectional flow area over its
length which is greater than the cross-sectional flow area of
the first mixer, the second mixer including a plurality of
static mixer elements serially arranged between an inlet and
an outlet of the second mixer for mixing the received media.
23. A method of mixing first and second fluid media of
differing viscosities comprising the steps of
providing a first mixer defined by an elongated first
tubular conduit having a first cross-sectional area and a
plurality of static mixer elements serially arranged in the
first tubular conduit over a length thereof for mixing the
media;
forming a first flow of the media through the mixer
elements;
flowing the first flow substantially parallel to the
first tubular conduit;
with the first flow substantially completely occupying
the first cross-sectional area of the conduit;
providing a second mixer defined by an elongated, second
tubular conduit having an inlet in flow communication with the
first tubular conduit, an outlet and a second cross-sectional
area which is greater than the first cross-sectional area, and
a plurality of static mixer elements arranged longitudinally
over a length of the second conduit;
at the inlet of the second mixer receiving the first flow
and with it forming a second flow of the media;
flowing the second flow over the length of and
