Description:
The description and prediction of the highly transient processes on molecular scale in gas-liquid Taylor flows in microchannels are a great challenge. Due to a lack of in-situ measurement techniques offering a satisfactory spatial and temporal resolution, existing models and numerical simulation for reactive two-phase flows are poorly approved. The Raman spectroscopy and holographic system presented in this contribution overcomes shortcomings regarding the high temporal resolution and concomitantly occurring difficulties with high energy densities that have to be coupled into micro structured devices to operate with good limits of detection. It aims at gaining insight into the concentration profiles in the liquid phase within the microchannel to study the interaction between hydrodynamics, mass transport and reaction kinetics.
