| Popis: | Residence time experiments are used to study the single-phase flow hydrodynamics of a rotor-stator spinning disc reactor. Two reactor setups of different sizes are examined in order to identify the effects of the reactor’s operating parameters. In order to precisely determine the central moments of the reactors transfer functions, which allow conclusions on the fluid flow profiles in the gap, a deconvolution procedure in time as well as in frequency domain is established. Different residence time models are compared with regard to their applicability for deconvolution and fitting. The spatial extensions of the convectionally backmixed and the plug flow regions are quantified by means of a threshold method. Furthermore, the obtained results are incorporated into an engineering model and compared to literature. |
