Measurements of Turbulent Quantities in Complex Three-Dimensional Boundary Layer Flow
Artikel i vetenskaplig tidskrift, 1995

Measurements of the Reynolds stress tensor have been conducted with different techniques in the complex turbulent boundary layer of a curved duct, where the flow is changing from two-dimensional into a fully three-dimensional condition. Single-, cross- and triple hot-wire probes and a silicon based double-chip sensor were employed for measurements at a Reynolds unit number of 8 per meter. The Reynolds stresses were measured at a reference station in the two-dimensional part of the duct, and at five stations in the three-dimensional flow. Profiles of the different techniques were compared, and a good agreement was generally obtained between the investigated methods; however, deviations in certain parts of the profiles, due to prongs, probe body interference and influence of the size of the measuring volume were noted.
