• This work describes a numerical framework developed for the efficient and accurate simulation of microfluidic applications related to two leading experiments of the DFG SPP 1740 research initiative, namely the ‘Superfocus Micromixer’ and the ‘Taylor bubble flow’. Both of these basic experiments are considered in a reactive framework using the SPP 1740 specific chemical reaction systems. A description of the utilized numerical components related to special meshing techniques, discretization methods and decoupling solver strategies is provided and its particular implementation is performed in the open-source CFD package FeatFlow (FeatFlow Homepage, www.featflow.de, version from July 2020 [5]). A demonstration of the developed simulation tool is based on already defined validation cases and on suitable examples being responsible for the determination of the related convergence properties (in the range of targeted process parameter values) of the developed numerical framework. The subsequent studies give an insight into a parameter estimation method with the aim of determination of unknown reaction-kinetic parameter values by the help of experimentally measured data.
