Application of split-film anemometry to low-speed flows with high turbulence intensity and recirculation as found in electrostatic precipitators
Abstract
The operating characteristics of a split-film anemometer, as they apply to low-speed, high turbulence intensity flow, are presented in the form of response curves and calibration equations. Calibration equations suitable for finding the velocity normal to the film axis and the pitch angle by digital data reduction techniques are given. The effect of cooling due to flow parallel to the film axis is presented and the value of k is determined. Results show that the probe should not be used for turbulence intensities greater than 67% and that the pitch angle should be limited to 45 deg on either side of the plane of the split.
