The Role of Input Flows in Microfluidic Experimentations

Abstract In this paper we discuss the role of input flow to control the dynamics of air bubbles carried by water in a snake micro-mixer. In particular it was proved the importance of flow rate magnitude and frequency to accomplish the desiderated bubbles’ flow dynamics. Time series coming from microfluidic experimentation were analyzed by means of nonlinear measures (Largest Lyapunov exponent and divergence analysis) in order to obtain quantitative indicators of nonlinearity allowing the classification among different flow patterns.
