Abstract
The invention relates to a boundary layer probe for determining a fluid flow, comprising a measuring surface which is formed on a probe wall and with which a fluid flow to be determined is in contact during a measuring operation. The boundary layer probe also comprises an assembly of measuring obstacles that are formed in the region of the measuring surface as obstacles which disrupt the fluid flow in a flow region adjacent to the measuring surface, each of which has an elongated obstacle course extending over a particular obstacle length, and which are arranged at substantially equidistant angular distances in the circumferential direction. The boundary layer probe additionally has pressure measuring points, each of which is radially adjacent to an associated obstacle in order to detect a local pressure in the region of the measuring surface. The invention additionally relates to a measuring assembly and to a method for determining a fluid flow.
