Abstract
The authors deal with the use of X hot-wire probes for measurements of two velocity components. Using the effective velocity concept, four different analytical expressions for the yaw response of the hot wire signals have been considered. Using a set of reference calibration data the curve-fit accuracy of the four methods are first investigated. Then the related sum and difference signal analysis methods are compared and finally the velocity component errors caused by uncertainty in the value of the mean yaw angle are established.Keywords
