Abstract EN
The present paper reports the development and nonnulling calibration technique to calibrate a cantilever type cylindrical four-hole probe of 2.54 mm diameter to measure three-dimensional flows.
The probe is calibrated at a probe Reynolds number of 9525.
The probe operative angular range is extended using a zonal method by dividing into three zones, namely, center, left, and right zone.
Different calibration coefficients are defined for each zone.
The attainable angular range achieved using the zonal method is ±60 degrees in the yaw plane and −50 to +30 degrees in the pitch plane.
Sensitivity analysis of all the four calibration coefficients shows that probe pitch sensitivity is lower than the yaw sensitivity in the center zone, and extended left and right zones have lower sensitivity than the center zone.
In addition, errors due to the data reduction program for the probe are presented.
The errors are found to be reasonably small in all the three zones.
However, the errors in the extended left and right zones have slightly larger magnitudes compared to those in the center zone.
