This project will develop more robust designs of spray dryers that give greater flow stability and are more tolerant of process upsets than current conventional designs.
Chemical and Biomolecular Engineering
Such designs would be new developments that would address the challenging issue of reducing the deposition rates of particles on dryer walls, because this problem leads to significant downtime for cleaning. This project tackles important and outstanding research issues that are central to the advancement of science in this field: (i) Modelling the transient flow patterns of gas and particles in spray dryer designs at different process scales; (ii) Using this understanding to minimize the deposition rates of particles on dryer walls and the magnitudes and frequencies of flow instabilities by changing the designs and operating conditions; and (iii) Validating the deposition performance and flow behaviour of these new designs.
