Characterization Method for Separation Devices Based on Micro Technology
Design of microstructured process modules based on empirical approaches is time‐ and cost intensive. This becomes especially important for complex continuous operations, where several unit operations have to be efficiently combined for maximum process efficiency and economy. A concept for a model‐based design by an axial dispersion model is presented as a contribution to simplification and cost reduction. Simple microchannel structures with varying cross sections are evaluated with volume flows up to 20 mL min −1 . The predictive accuracy of the model is demonstrated and assessed by selected examples. Empirical layout of microstrutured process modules is time and cost intensive. Here, established methods for fluid dynamic characterization of micro devices are applied to meander‐type microchannels. For different channel widths and throughputs the predictive accuracy of the model is demonstrated and assessed with selected examples..
