  • A Miniature Four-Hole Probe for Measurement of Three ...

    A miniature four-hole probe with a sensing area of 1.284 mm 2 to minimise the measurement errors due to the large pressure and velocity gradients that occur in highly three-dimensional turbomachinery flows is designed, fabricated, calibrated, and validated. The probe has good spatial resolution in two directions, thus minimising spatial and flow gradient errors.
