Chapter 17
A Framework for Dynamic Simulation
of Interconnected Solids Processes
Vasyl Skorych, Moritz Buchholz, Maksym Dosta, and Stefan Heinrich
Abstract The application of flowsheet models to dynamic solids processes pose
significant challenges, especially regarding the handling of the inherent multidimensionality of granular material properties, like particle size, shape and porosity distributions. The novel open-source flowsheet simulation framework Dyssol deals with
this by applying an approach based on transformation matrices, which allows for the
tracking of temporal changes in the multi-dimensional distributed parameters of the
granular materials. The modelling system utilizes the sequential-modular approach
in combination with partitioning and tearing methods as well as the waveform relaxation method for increased modelling flexibility while offering high computational
performance. Dyssol includes an extensive and expandable model library for various
unit operations in process engineering, that in turn may be calculated by user-defined
solver units from a distinct library. To enhance the computational performance, the
user may choose from different convergence and extrapolation methods. Material
properties are defined in an extendable material database. Various case studies show
robust stability and high convergence rates. The application of a global optimization
algorithm shows promising results for the operational parameter adjustment in case
of transient system behaviour. A concept of applying artificial neural networks to
extend the scope of dynamic flowsheet simulation systems is proposed.
