Abstract

Uncertainty analysis of hot-wire data in turbulent flows are made for time-averaging and real-time data reduction techniques. Equations of uncertainty are derived in general form for every step of data taking and evaluation. Numerical examples are supplied for two-dimensional flat plate boundary layer data. Results show that the real-time data reduction techniques generally have a lower and much more uniform uncertainty distribution than the time-averaging techniques (whose uncertainties are much higher for the near-wall data).
