Abstract
A mixer having a unitary construction is disclosed comprising an annular housing having an axis and at least a first swirler having a plurality of vanes arranged circumferentially around the axis such that circumferentially adjacent vanes form at least one flow passage that is oriented at least partially in an axial direction with respect to the axis. In another exemplary embodiment, a mixer having a unitary construction is disclosed comprising a swirler having a plurality of radial vanes arranged circumferentially around the axis and oriented at least partially in a radial direction.

A unitary mixer comprising:
- an annular housing having an axis;
- and
- at least a first swirler having a plurality of vanes arranged circumferentially around the axis such that circumferentially adjacent vanes form at least one flow passage that is oriented at least partially in an axial direction with respect to the axis.
A unitary mixer comprising:
- an annular housing having an axis;
- and
- a swirler having a plurality of radial vanes arranged circumferentially around the axis such that circumferentially adjacent vanes form at least one flow passage that is oriented at least partially in a radial direction with respect to the axis.
A unitary mixer comprising:
- an annular housing having an axis;
- a first swirler having a plurality of radial vanes arranged circumferentially around the axis such that circumferentially adjacent vanes form at least one flow passage that is oriented at least partially in a first radial direction with respect to the axis;
- a second swirler located axially aft form the first swirler having a plurality of radial vanes arranged circumferentially around the axis such that circumferentially adjacent vanes form at least one flow passage that is oriented at least partially in a second radial direction with respect to the axis;
- and
- a third swirler located axially aft form the second swirler having a plurality of radial vanes arranged circumferentially around the axis such that circumferentially adjacent vanes form at least one flow passage that is oriented at least partially in a radial direction with respect to the axis that is different from the second radial direction.
