Doctoral Student Stefan Heidinger presents new publication
The latest paper entitled "Simple Particle Relaxation Modelling in One-Dimensional Oscillating Flows" (DE: "Einfache Modellierung der Partikelrelaxation in eindimensionalen oszillierenden Strömungen") by doctoral student Stefan Heidinger (Subproject A2: Theoretical and experimental investigation of process boundary conditions in pulsating flows for the production of novel oxidation catalysts) and the Chair of Energy Process Engineering has now been published.
The paper investigates the possibility to model the motion of solid particles in oscillating flows (gas or liquid) through a few input parameters with a very large parameter range. This is done analytically and graphically, comparing different models for flow resistance. The figure below shows the heart of the paper - a plane spanned using the two central parameters Reynolds number (Re) and amplitude parameter (ε). All flow states of a particle in a one-dimensional oscillating flow can be recorded in it. This research is modeled on the process conditions in a pulsation reactor, in which a few process parameters play a central role, but which can be adjusted over a wide range of values.
