NR 062-414/6-6-68(Code 438), U.S. Department of Defense.A hot-wire anemometer for measuring turbulence in three-dimensional mean flow is presented. Effect of three-dimensionality of mean flow on a yawed wire's sensitivity to longitudinal, vertical and lateral fluctuations is brought out. A four-wire probe is shown to be suitable for measuring all the Dean flow and turbulent quantities of interest. Errors due to the cross flow component on turbulence measurements in two dimensional flows using conventional hot-wire techniques are estimated. Measurements of shear are shown to be very sensitive to even small amounts of cross flow that might be present in many laboratory and field flows of interest.technical reportsengCopyright and other restrictions may apply.
