Experimental and Numerical lnvestigation of Competitive Chemical Reactions on Different Scales in Milli Reactors

By: Frey, Torben

The application of modular continuous-flow equipment enables more efficient and greener chemical processes through precisely defined process windows and new synthesis pathways. Despite the advantages, continuous-flow processes are sparsely favored over large-scale batch processes in the chemical industry due to today's lack of detailed understanding of micro mixing performance and selectivity of chemical reactions in laminar flow regimes. This thesis reviews and proposes numerical and experimental methods for quantifying micro mixing and its influence on selectivity in competitive chemical reactions. The transport properties of a laminar-flow liquid-liquid mixing problem with chemical reactions is investigated by experimental and numerical methods. A modular split-and-recombine (SAR) mixing unit is used as a benchmark geometry. First, direct numerical simulations (DNS) are performed for a range of Reynolds and Schmidt numbers (1
