Abstract
Five-hole probe used in a non-nulling manner to find unknown flow properties is limited to a low range of acceptance angles due to singularity encountered in the calibration procedure. A novel method to extend this range by avoiding singularity is developed allowing calibration of a five-hole probe up to much larger angles of pitch and yaw. The method has been tested using experimental calibration data of a five-hole probe that were obtained employing the 18in. × 18in. subsonic closed circuit wind tunnel of the University of New South Wales at the wind tunnel speed of 15 m/s. The new procedure shows that the calibration range can be successfully extended to angles of up to ±75°. A step-by-step procedure of using the new technique is also detailed in this chapter.
