AN INVESTIGATION OF CYLINDRICAL STATIC PRESSURE PROBES.
Abstract
The cylindrical pressure probe is a convenient device for the measurement of the static pressure of a fluid stream. The indicated pressure, however, is a function of the angular position of the probe relative to the direction of flow. It is therefore necessary to know the probe angular position at which true static pressure is indicated for the probe-flow situation at hand. In this study values of the probe angular position are determined for ten different probe geometries in a Reynolds number range from 2,500 to 15,000. The method used was to place the probes in a stream of air that is being ejected into the atmosphere. The static pressure of such a stream is equal to the local barometric pressure. Plots of the results show the dependence of the probe angular position on probe diameter, orifice diameter, and Reynolds number.
