Influence of the Reynolds number on the statistical and correlation-spectral properties of turbulent swirl flow
Апстракт
Average velocity distributions of the turbulent swirl flow for four Reynolds
numbers, obtained with one-component laser Doppler anemometry (LDA) and stereo
particle image velocimetry (SPIV) behind axial fan in the pipe, has been reported in
this paper. The highest levels of turbulence are observed in the vortex core region as
well the non-Gaussian values for skewness and flatness factors. Additional
information on turbulent structure physics were obtained on the basis of
experimentally determined autocorrelation functions and time integral scale for
circumferential velocity.
