Abstract

The material contained in this monograph has been divided into six main sections, in accordance with the specific applications of the pitot tube and other allied pressure probes, viz. for impact pressure, static pressure, dynamic pressure, flow direction and vector velocity, skin friction as well as flow measurements. In most instances, as far as it could be managed, the author has tried to incorporate both theoretical and experimental aspects on the various factors influencing the accuracy of the pressure probes. It is, therefore, hoped that this monograph can serve as a useful sequel to the monograph by Bryer and Pankhurst, entitled “Pressure-probe Methods for Determining Wind Speed and Flow Direction”, adding further details on topics discussed therein and other topics not already included.

It is the intention of the author to exclude discussions on the use of pressure probes for static-pressure fluctuation measurements. This is a highly specialized field of application and the only reliable measurements at the present seem to be those of Elliott (J. Fluid Mech., 53 (1972) p. 351).

The author takes great pleasure in acknowledging the assistance rendered by Mr. P. Bradshaw of Imperial College in the preparation of this manuscript, for his advice and suggestions on matters related to this paper, and is also grateful to him and Prof. Küchemann for suggesting several extra references.

      For these two types of Pitot tubes, they saw that the calibration factor varied within ±0.1% or ±0.2% at speeds above 4 m/s; the maximum variation of the calibration factor is ±0.5% in the speed range of 1.8 m/s to 3.7 m/s, and the calibration factor varies from ±1% to ±2% at speeds lower than 1.2 m/s. On the other hand, Care and Fourneaux [10] found out that the pressure response depends on the design of the Pitot tube, and the resistance of the static pressure line mainly related to unexpected fluctuations of flow. Chue [11] briefly outlined the generalized dimensions of several common Pitot tubes and discussed factors that cause measurement errors. However, no quantitative suggestion related to the calibration factor was given.

      For flow measurements using an orifice plate, nozzle, Venturi meter, pitot tube or similar, the differential pressure is generally measured through a wall tap. Well-known sources of static pressure measurement error are edge roundness or burrs on the wall tap corner and the inclination of the wall tap [1,2]. However, even if the wall tap is manufactured to be perpendicular to the wall and its edges are sufficiently sharp, a static pressure measurement error is induced due to cavity flow within the tap [3].

      A 3-axis traversing system controlled by a computer ensures the displacement of the Pitot probe with a step resolution on each axis of 0.12 mm ± 0.02 mm on each position. Despite low pressure conditions, no orifice corrections due to viscous effects have to be applied to the pressure measurements probes [20,21] Fig. 3. Commonly techniques such as PIV or Schlieren used to visualize flow fields around models cannot be applied because of the low pressure operating conditions, especially for the N1 and N2 nozzles.

      The measured pitot pressure is normally used to derive the flow velocity or the volumetric flow rate in steady/quasi-steady flows [1,2]. Folsom [5] and Chue [6] provided comprehensive reviews of the Pitot tube technique, and summarized various tube designs and calibration methods. However, the response rate of conventional Pitot tubes is too low for the transient pressure measurement in impulse facilities.
