MODELING OF COMPLEXATION PROCESSES IN A MICROFLUIDIC CHANNEL
This work proposes a mathematical model that describes polymer surfactant complexation in microfluidic confinement. A system of nonlinear differential equations has been developed to characterize kinetics of polymer surfactant interaction in 100-300 µm microchannel convection diffusion conditions with the consideration of Hagen Poiseuille parabolic velocity profile. Numerical solution of these equations has been obtained with Matlab Partial Differential Equations Toolbox. Three dimensional concentration distribution profiles of complexation products in microchannels been analyzed. Simulation results have been compared with the respective experimental data obtained with microfluidic devices.
