Influence of Different Sensor Configurations on the Turbulent Quantities in a Complex Three-Dimensional Flow Field

Löfdahl, Lennart,1948Chalmers tekniska högskola,Chalmers University of Technology (author)

Measurements of the Reynolds stress tensor have been carried out in a complex three-dimensional boundary layer using different techniques. Single-, cross- and three-hot-wire probes were employed together with a silicon based double chip sensor. All measurements were performed at a Reynolds number of 1.2 x ___ per meter. The turbulent stresses were determined at a reference position in a two-dimensional part of the flow field and at three locations with different strength of the three-dimensionality. A good agreement was found in the turbulent quantities measured with the different methods, however, the influence of prong interference, measuring volumes and velocity gradients were noted.
