Abstract
Single inclined hot wires and X-wires are calibrated directly for absolute turbulence intensity measurements by oscillating the wire probe sinusoidally with accurately known motion in a steady stream. The usual static method of calibration shows serious discrepancies and uncertainties when compared with this new procedure. The new method also provides a check on the small perturbation linearity of inclined wires.Keywords
