Process and System Modelling


PACT’s process or system modelling capability, drawing on extensive modelling expertise within the Consortium, including European Centre of Excellence of Computational Fluid Dynamics at the University of Leeds.

PACT facilities are integrated pilot scale facilities with significant analytical capability. The integrated approach of advanced computational modeling, detailed experimental testing, and imaging form a mutual validating and complementary system to ensure a credible output so that an in-depth understanding of the impact of flame characteristics, critical reaction kinetics, and devolatilsation and char reaction in the combustion processes. These create a unique and powerful combination for the development of models for individual processes and integrated systems.

The core facility’s computational modelling capabilities are based at the PACT Office in Sheffield with multiple modelling stations preloaded with modelling and other relevant software including Fluent, Aspen, Chemical Kinetic and CAD Drawing software to support research and consultancy activities. PACT via the University of Leeds has commercial licences for industry standard modelling software packages, which means it can provide commercially ready solutions to companies.

Example Applications

  • Combustion flame modelling for different fuels and combustion conditions (oxyfuel, high oxygen with coal and biomass,…) to aid burner and plant design, or assessment of system flexibility, or evaluation of impact of using new fuels or operating conditions on system stability and energy and environmental performance.
  • Modelling of new carbon capture media to assess system flexibility and performance with different fuels and under different conditions, aid system optimisation and techno-economic analysis.
  • Whole system modelling of High oxy-biomass post combustion system to aid plant design in terms of scale and operational requirements of components, optimum operating conditions and component and system tolerances
