Characterization of a reactor module by means of 3–Dimensional finite element - analyses

Based on flow models applied in former analyses, three dimensional numerical flow simulations were performed for a spherical reactor cell of a biological monitoring module with respect to different inflow configurations and respective mass flow rates. Time - dependent simulations were performed for the case of dyed water and clear water flowing through different inlets at varying mass flow rates into the spherical cavity of reactor cell and channel system which connects the relevant measuring ports of the monitoring module. Spectroscopic analyses of light absorption at a port have been carried out and the results compared with the local concentration distribution predicted for this port by means of FE - analyses (Finite Element) using the CFD (Computational Fluid Dynamics) - program package of Fluent Inc.
