Abstract
Split-film probes have been applied to the measurement of turbulence properties in an intermittent reverse-flow region. Two kind of split-film probes of O. 153mm diameter (manufactured by KANOMAX Co. Ltd.) are employed to ne has the split plane normal to the main flow and is able to measure the longitudinal velocity component and reversals of flow direction; the other has the split plane parallel to the main flow and measures the lateral velocity component. Their response to the magnitude and direction of the velocity vector is statistically calibrated in a uniform flow in a wind tunnel. The frequency response of the probe is checked by comparing the longitudinal velocity spectra with those obtained by a single hot-wire probe in a grid-generated turbulence. The split-film probes are used to measure the reverse-flow region in the separation reattachment flow formed at the leading edge of a blunt flat plate with square corners. The time-mean，root-mean-square values of the fluctuating velocity and the reverse flow intermittency are successfully obtained by the split-film probes.
