Nozzle with guiding elements

摘要

The nozzle has guide vanes (10) arranged circumferentially around its edge (9). Further guide vanes (20) are included. One type of guide vane is diffuser-like; the other is nozzle-like. The first guide vane (10) has two sidewalls running at an angle to the flow direction (6). It (10) is connected to two adjacent, second guide vanes (20) by these sidewalls. They also separate the diffuser- and nozzle flows at the edge of the nozzle. The guide vanes (10, 20), form alternating trapezia; these converge and diverge in the flow direction.
