Pressure probes for fluid measurement

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. Kuchemann for suggesting several extra references.
