Combined population balance and thermodynamic modelling of the batch top-spray fluidised bed coating process. Part I—Model development and validation

Comparison and evaluation of interphase momentum exchange models for simulation of the solids volume fraction in tapered fluidised beds

“…The SSR is a measure of the model's deviation from the experimentally measured solids volume fraction (Ronsse et al, 2007). It was calculated as…”

“…Among the wide range of microencapsulation techniques, fluidised bed technology has been successfully used for the coating of particulate solids due to its excellent mixing capabilities and its optimal heat and mass transfer rates Huyghebaert, 1998, 1999;Ronsse et al, 2007). Moreover, this technology has proven to be applicable in different industries, e.g.…”

Modelling side-effect spray drying in top-spray fluidised bed coating processes

“…The simulation method, described by Ronsse et al (2007a), was used for the simulations in this study. To summarise, the proposed method solves the population balances by simulating a finite number of particles, distributed over n control volumes.…”

“…Consequently, the amount of coating material collected by a single particle is a function of the number of passes and the residence time of each pass in these spraying or coating compartments. Ronsse et al, 2007a,b proposed a compartment model which combined population balances to describe the solid phase (particles) with a heat and mass transfer model. This model enabled the prediction of both the dynamic coating mass distribution and the one-dimensional thermodynamic behaviour of the fluidised bed during batch coating operation.…”

Modeling of layering growth processes using a Monte Carlo approach

“…crystallization, see Gerstlauer et al (2006) and Randolph and Larson (1972), and layering granulation, see Heinrich et al (2002), Ronsse et al (2007) and Silva et al (2011). The properties of the particles are represented by external and internal coordinates.…”
