Our new article "On the role of energy dissipation in a dynamically structured fluidized bed” has just been published in Chemical Engineering Science. It can be downloaded .
In this work, former CNIE researchers (now Assistant Professor at Heriot-Watt University) and (now at TU Delft) with Prof Marc-Olivier Coppens (CNIE Director) describe the fundamental self-organisation mechanisms (associated to CNIE’s Theme 3) underpinning a new type of fluidised bed operation that can maximise the efficiency of particle manufacturing processes (e.g. pharmaceuticals and specialty chemicals), allowing to mix solids efficiently at low velocity and in a controllable and scalable fashion. “Dynamically structured fluidization” utilises an oscillatory gas flow to create an ordered flow of bubbles in a bed of powder. Using experiments and CFD-DEM simulations, the researchers explain the origin of this ordered flow and describe how inter-particle friction is the key to determine its scale and stability.
