Axi-asymmetric character of turbulent swirling flow in a straight circular pipe
Abstract
Swirling flow in a pipe usually has some axiasymmetricity, detail of which has not been clarified. Here, detailed experimental investigations concerning axiasymmetric characteristics of velocity distributions and especially the eccentricity of swirl centers were performed. Small deviation of velocity distribution from symmetry at inlet section causes nonnegligible asymmetricity in downstream section. This increase of asymmetricity in downstream section occurs only in a certain swirl-intensity range. In addition to the velocity distributions, the axiasymmetric characteristics of momentum field and wall pressure are also given.
