Nonlinear Dynamics in Experimental Two-Phase Microfluidics Timeseries

In this work experimental studies on nonlinear dynamics in two phase microfluidics were carried out. Nonlinear analysis methods were applied to time series coming from experimentation in microfluidics. The time series were captured using high sensitive photodiodes on a magnified image of the microfluidic phenomena under investigation, and they represent the time domain dynamics of a two phase flow in an in vitro serpentine mixer, in particular of bubbles flow patterns. This study allows capturing significant chaotic features in the time domain for different experimental conditions, and it is useful for a first understanding of two phase flow patterns in complex microchannels.
