主 题:Single particle dissolution Computational fluid dynamics Direct numerical simulation X-ray micro-tomography
摘 要:A coupled approach between the conventional computational fluid dynamics platform COMSOL and an in-house-developed direct numerical simulation code DigiDiss is presented to study the dissolution kinetics of an irregular-shaped particle in a stirred *** complex flow dynamics from COMSOL were imported into DigiDiss as an initial flow condition.A digitised 3D particle structure scanned and reconstructed by X-ray micro-tomography was used in the dissolution simulation.A quantitative assessment of the simulation results was made using as a reference experimental data and a theoretical calculation based on the shrinking spherical model with different flow velocity profiles near the *** comprehensive agreement demonstrates the coherence of the simulation method in reproducing the experimental behaviour and is seen as a step closer towards developing a computer software design aide to help with formulation development.
