Qualification of a Photometer Probe for Local Concentration Measurement in Dense Bubbly Flows
Hampel, U.; Kryk, H.; Kipping, R.;
Topics of current research activities within the DFG priority program SPP 1740 “Reactive Bubbly Flows” are studies on local mass transfer and reaction processes in order to gain a deeper understanding about the coupling of hydrodynamics, mass transfer and reaction kinetics in reactive bubbly flows as well as its influence on yield and selectivity in case of complex chemical reactions. Precondition for experimental investigations is the availability of sensors for local concentration measurements of components in the liquid phase. Due to limitations of currently available non-invasive measuring techniques, local concentration measurements in dense bubbly flows at technical scale pose technological challenges. Therefore, a minimal-invasive photometer probe have been qualified to measure concentrations of intermediates and products within the liquid phase of dense bubbly flows with high temporal and spatial resolution.
This work was supported by the German Research Foundation (DFG), reactive bubbly flows (SPP 1740).
