Correlation Analysis of the Frequency of Gas Single-Phase Flow and Gas-Solid Two-Phase Flow Through the Same Piping

摘要

In the same piping, the gas transporting medium enters from one end of the piping, and the solid powder as transported medium enters from the middle of the piping, so the input of piping is single-phase gas flow, and the output of the piping is gas-solid two-phase flow. Getting information from vibration sensor, measuring the piping signals of gas single-phase flow and gas-solid two-phase flow, using the band-pass specialty of wavelet function in wavelet transform, eliminating the noises in the signals by Mallat's maximal module algorithm, using the method of frequency spectral analyzing, we can study the variety disciplinarian of energy spectrum and frequency spectrum of piping gas single-phase flow and gas-solid two-phase flow signals, and also the corresponding correlations in the concentration variety of the solid powder in gas-solid two-phase flow.
