摘要: Abstract A method was established to quantitatively describe nonlinear dynamic behavior of heterogeneous flow structure in gas–solid fluidization by carrying out multiple resolution and time series reconstruction experimental signals. Optimum sampling frequency proposed analyzing the dependence Kolmogorov entropy on frequencies. Original signals could be resolved with respect first scale, then amplitude into a periodic function three irregular changes (micro-scale fluctuations, meso-scale fluctuations). Statistical analysis indicated that kinds components are random characteristics, complicated evolution their probability density distributions changing operating conditions. new distribution function, called Compound Weibull seven parameters, developed fluctuations structure, leading model for simulating behaviors fluidization, which has been coded software package.
