Abstract:
1. A nozzle, comprising: a nozzle rim; a plurality of first guiding elements circumferentially arranged at the nozzle rim; a plurality of second guiding elements circumferentially arranged at the nozzle rim, with one of the first and second guiding elements being diffuser-type and the other of the first and second guiding elements being nozzle-type and with both types of guiding elements circumferentially alternating with each other; wherein the diffuser-type guiding elements each have two substantially radially extending and planar side walls circumferentially diverging in a flow direction from an upstream entry area to a downstream exit area with the two diffusing side walls forming an angle with respect to one another having a vertex upstream of the diffuser-type guiding element; wherein the nozzle-type guiding elements each have two substantially radially extending and planar side walls circumferentially converging in a flow direction from an upstream entry area to a downstream exit area with the two converging side walls forming an angle with respect to one another having a vertex downstream of the nozzle-type guiding element.
