Pressure Probes Selected for Three-Dimensional Flow Measurement

摘要

Seven pressure probes have been tested in a uniform stream in order to ascertain the best types for measuring velocity and flow direction. Methods of calibration are discussed in section 3 together with the effects of wind speed, flow direction and turbulence on the calibration factors (section 4).nThe performance of three of the probes in the turbulent boundary layer of a flat plate is analyzed and their accuracies compared when they are used to estimate displacement and momentum thicknesses (section 6).
