Complex gas-liquid reactions with mass transfer in coiled capillaries

The project aims to optically investigate the mass transport and selectivity of gas-liquid color reactions in capillary reactors of different geometries and better to understand them with the aid of high-resolution 3D simulations. The capillary reactors considered are the straight capillary, the curved capillary and the so-called coiled flow inverter (CFI). Biocatalytic reaction systems are used as color reactions, since they are often more advantageous than chemical reaction systems concerning their longer reaction time.
