Abstract
The discrete wavelet transform was applied to experimental pressure-time signals in this paper, in order to analyze the characteristics of the gas-solid two-phase flow in both Fourier and physical spaces. From randomlike pressure fluctuations, the fluctuating pressure components due to dispersed suspension flow and dune flow can be extracted over a time-scale plane based on the wavelet 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 of dune flow.
