An experimental study of the turbulent velocity field structure was performed in a pipe flow. The primary objective of this study was to provide a detailed velocity field structure, under isothermal conditions, for use as a reference condition for later investigations of the interactions between fluctuating velocity and temperature fields, under non-isothermal conditions, in turbulent pipe flow.

Two-point, two-component (u1 and u2) velocity correlation measurements were made with hot-film ('x' probes) anemometers separated in the radial direction as well as two-point axial component correlation measurements with axial separation.

The fluctuating signals were analyzed digitally and both space and space-time correlations were calculated.

Spatial scales for each velocity component were determined and then used in the modeling of two-point space correlations in terms of axisymmetric tensor forms. Finally isocorrelation curves were evaluated from the axisymmetric models to test their prediction capabilities.
