Wind channel arrangement and method for determining aerokustischer properties

摘要

The present invention relates to a wind channel arrangement (1) with a nozzle (4), which a nozzle entry (44) for receiving a generated air flow (60), a nozzle outlet (45) for the output of the air flow (60) arranged between them and a contraction (40) for the acceleration of the air flow (60) from the nozzle entry (44) to the nozzle outlet (45), and with a vorkon traction region (50), which is located upstream from the nozzle entry (44) is arranged, by means of which, in the vorkon traction region (50) and / or in the contraction (40), a turbulence generating arrangement (30) is formed, which one or more turbulence generating elements (35), and a respective turbulence generating element (35) for the generation of turbulence of the flow (60) can flow.
