WAVELET ANALYSIS OF UNSTEADY CHARACTERISTICS IN SWIRLING GAS-PARTICLE FLOW

Résumé

The multiresolution analysis and multiresolution cross-correlation analysis were applied to experimental pressure-time signals in this paper, in order to analyze the characteristics of swirling gas-particle two-phase flows in both Fourier and physical spaces. From randomlike pressure fluctuations, the fluctuating pressure components due to dune flow can be extracted over a time-scale plane based on the multiresolution analysis. It was found that the dominant scale of the heterogeneous suspension flow over the dunes increases along flow direction and reaches 0.017s in the fully developed region. The multiresolution cross-correlation analysis revealed that dunes with same moving velocity of 1m/s pass through test pipeline and non-correlation existed at smaller scales that represent heterogeneous suspension flow over the dunes.
