Fluid flows with chemical reaction and particle formation; interaction of turbulence with chemical reactions and particulate processes; advanced modelling and simulation methods. Applications include combustion, mitigation of pollutant formation, turbulent mixing and production of nanoparticles.

Mathematical methods for mechanism reduction

show research

  - Rate-Controlled Constrained Equilibrium (RCCE)
  - Methods for selecting leading species for RCCE, including Computational Singular Perturbation (CSP)

Coupling of kinetics and fluid dynamics

show research

  - Artificial Neural Networks (ANN) including regression networks (Multi-Layer Perceptron, MLP) and classification networks (Self-Organising Map, SOM) for tabulating combustion mechanisms
  - Generation of comprehensive data sets for ANN tabulation via abstract combustion problems

Reacting flows with particle formation

show research

  - Population balance modelling of particulate processes, numerical methods for solution of the population balance equation (PBE)
