Dynamic flowsheet simulation of interconnected solids processes

This thesis presents Dyssol – a novel simulation framework for dynamic fl owsheet simulation of solids processes. Designed as a versatile, modular, and extensible tool, the system addresses the challenges of dynamic modelling of complex process structures with interdependent unit operations and recirculation fl ows. Particular attention is given to accurately representing the multidimensional distributed properties of granular materials, such as particle size, porosity, and composition. Advanced numerical algorithms ensure high computational performance and stability in calculations. The system’s applicability and versatility are demonstrated through various case studies across diff erent application domains. Dyssol is released as open-source software, enabling its use in education, research, and industry. This work provides the community with a comprehensive platform for developing new models and methods, studying transient behaviour, and analysing and optimising various inter connected solids processes.
