Particle agglomeration is an important and common phenomenon in (wet) fluidized beds. Fundamental understanding of the micro-mechanisms of particle agglomeration and their impact on the macroscale dynamics of the bed is essential both in agglomeration-desirable processes (e.g granulation and spray drying) and processes where agglomeration in unintentional (e.g. combustion and gasification). However, the current understanding is limited to idealized systems involving e.g. water, axisymmetric liquid bridges and spherical particles. With the current consortium, we want to extend research to more realistic systems involving complex fluids (viscoelastic fluids
) and complex solids (polydispersity
and non-spherical particle
The project has two main objectives
[PhD @ SMR] To obtain a comprehensive understanding of the dynamic liquid bridging,
[PhD @ PF] To understand the interplay between the agglomeration and the macroscopic flow dynamics in wet fluidized beds.
Both objectives will be reached using Computational Fluid Dynamics (i.e. Particle-Resolved Direct Numerical Simulations and Computational Fluid Dynamics coupled with Discrete Element method, respectively). The results of these numerical methods will be validated using dedicated experiments which will be performed in close collaboration with the Hamburg University of Technology (TUHH).Project team
You will work in a collaborative team which include dr. Yali Tang, prof. Niels Deen (PF) and dr. Maike Baltussen, prof. Hans Kuipers (SMR) from Eindhoven University of Technology (TU/e) and prof. Stefan Heinrich from TUHH. You will be employed at TU/e, however this collaboration requires you to pay short-term visits to the group of Prof. Heinrich.
