Abstract
A split film sensor is preferred over an X-wire probe for the measurement of reverse flow fields. However, the prevailing calibration techniques for the split film sensor are reliable for small pitch angles only. In this study, Stock's method for pitch angle response is improved to provide a more reliable calibration for a wide range of velocity magnitude and pitch angle. To show its usefulness, the proposed method is applied to a turbulent reattaching flow behind a rearward-facing step. The measured data compare favourably with those measured using conventional hot-wire anemometry.
