Comparison of FEM and DPB Numerical Methodologies for Dynamic Modeling of Isothermal Batch Gibbsite Crystallization
A population balance equation based dynamic gibbsite crystallization model, incorporating crystal growth, nucleation, and agglomeration, was solved using two different numerical techniques, namely, aExpand

2-D sizing of sodium oxalate crystals by automated optical image analysis
Abstract A new automated static optical image analysis (SOIA) method was developed for characterising the shape of sodium oxalate crystals by separately measuring their length and width. TheExpand

An Unreacted Shrinking Core Model for Calcination and Similar Solid-to-Gas Reactions
A variation on the unreacted shrinking core model has been developed for calcination and similar non-catalytic solid-to-gas decomposition reactions in which no gaseous reactant is involved and theExpand

A multi-stage, multi-reaction shrinking core model for self-inhibiting gas–solid reactions
Some thermal decomposition reactions display self-inhibiting behaviour, where the produced gas negatively influences the reaction progress. Further, a build-up of internal pressure caused by theExpand

Numerical Modelling of Stress Effect on Grain Contacts and Elastic Properties ofUnconsolidated Sandstone
Impact of discontinuities on rock elastic properties is a long-standing problem in rock physics. Grain contacts, one of the most common type of discontinuities, are responsible for nonlinearExpand
Understanding oscillatory behaviour of gibbsite precipitation circuits
Abstract Gibbsite precipitation plays a central role in the production of alumina, the feedstock for aluminium smelters. A mathematical model of a simplified precipitation circuit is used in thisExpand

A two-phase solution procedure using mixtures of algorithms in the structure–property problem
Prediction of the properties of chemical compounds by mathematical methods of pattern recognition is considered. Expand
Multi-stage shrinking core model for thermal decomposition reactions with a self-inhibiting nature
Among the variety of thermal decomposition reactions, some display self-inhibiting behaviour, where the produced gas negatively influences the reaction progress. Further, a build-up of internalExpand

Modelling of gibbsite calcination in a fluidized bed reactor
A steady state, non‐isothermal fluidized bed reactor model for co‐current flow of gas and solids has been developed as a series of Continuous Stirred Tank Reactor (CSTR) compartments. For each CSTRExpand
A PDE Agglomeration Model for Bayer Precipitation
A dynamic gibbsite precipitation model based on Safronov agglomeration equation and its newly derived partial differential equation (PDE) approximation. Expand
