Abstract
The use of single and multiple hot-wire/hot-film probes for subsonic flows is discussed with emphasis on the digital methods and procedures. An account is given of the major factors which influence the reliability of measurements and the application of many of the correction procedures required. The factors considered are: probe calibration, nonlinearity of the sensor-response equation, temperature effects, temporal and spatial resolution and probe design.Keywords
