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).
