In the paper the method based on recurrence plots has been used for identification of two-phase flow in a vertical, circular minichannel. The time series obtained from image analysis of high speed video have been used. The method proposed in the present study allows us to define the coefficients which characterize the dynamics of two-phase flow in a mini channel. To identify two-phase flow patterns in a mini channel there has been used the coefficient LAVG which is a measure of an average length of diagonal lines in recurrence plot. The following two-phase flow structures have been considered: bubbly, bubbly-slug and wavy-annular. Obtained results show that method proposed in the paper enables identification of borders between two two-phase flow patterns coexisting in a mini-channel.
