Abstract

An experimental method for the formation characteristics of co-flowing focusing microbubbles based on polydimethylsiloxane (PDMS) microfluidic chip is introduced. An experimental system was set up to investigate the effects of liquid flow rate, gas pressure and gas channel width on bubble detachment volume and formation time. Based on the assumption of ellipsoid theory, the theoretical model for volume prediction of co-flowing focusing microbubbles is established. The numerical solution of the model is obtained by the fourth-order Runge-Kutta method. The results show that the prediction results of theoretical model correlate well with the experimental data.
