It is the key issue of two-phase flow research to identify the flow type. The variability of two-phase flow medium leads to diversity and randomness of two-phase patterns

so it is difficult to identify the flow pattern effectively. Thinks to independent component analysis (ICA) fixed point algorithm

featuring fast convergence speed and no need of the introduction of some iterative process parameters

such as regulated step

in this paper the method named ICA-RBF was developed

which included two steps:first

applying the fixed point algorithm of negative entropy to extract convection-type characteristic parameters; second

identifying the parameters by radial basis function(RBF) neural network. Moreover

other two means

i.e. wavelet packet decomposition and singular value decomposition were introduced to extract feature from the same set of data. Through experimental comparison

it was concluded that ICA-RBF had better recognition results as well as simpler inspection process steps

which could reduce a lot of man-made errors and obtain more accurate and convincing result.It is the key issue of two-phase flow research to identify the flow type. The variability of two-phase flow medium leads to diversity and randomness of two-phase patterns
