Measurement of hydrodynamic non-uniformities and their dynamics in porous particle packings using capacitance wire-mesh sensors

Despite intensive work in the past decades, hydrodynamics of the widely used trickle bed reactors are still on the focus of today’s research. There are a lot of questions and obstacles to be solved and simple but accurate and reliable measurement devices to be developed. In this study we present a new capacitance wire-mesh sensor system applied to a trickle bed reactor to investigate steady-state and dynamic hydrodynamic characteristics allowing to get new insights into the temporal and spatial behaviour of the trickle flow and pulse flow.
