Nonlinear analysis of mineral wool fiberization process

Bizjan, Benjamin (author), Širok, Brane (author), Govekar, Edvard (author)

In this paper, mineral wool fiberization process on a spinner wheel was studied by the means of the nonlinear time series analysis. Melt film velocity time series was calculated using computer-aided visualization of the process images recorded with a high speed camera. The time series were used to reconstruct the state space of the process and were tested for stationarity, determinism, chaos and recurrent properties. Mineral wool fiberization was determined to be a low-dimensional and nonstationary process. The 0-1 chaos test results suggest that the process is chaotic while the determinism test indicates weak determinism.
