Abstract
An automated rig has been constructed to allow continuous monitoring of the probe steady-state calibration during the measurement of the Reynolds stress tensor in turbulent single-phase flow using a two-channel hot-wire anemometer. The system consists of a signal switching and signal gain control unit, remote probe positioning along three coordinates, and a PDP11/10 computer for on-line data analysis. The system was calibrated using fully developed single-phase turbulent pipe flow; the results showed good agreement with published data. The calibrated system had been used to map the Reynolds stress field in three-dimensional duct flows having a similar turbulence level to developed pipe flow.
