Presentation transcript:

1 Advanced modelling for turbulent combustion (among other things) Edward S. Richardson: “I am an old man now and when I die and go to heaven there are two matters on which I hope for enlightenment. One is quantum electrodynamics, and the other is turbulent motion of fluids. And about the former I am rather optimistic.” [Horace Lamb] Lagrangian particles tracking the turbulent flow in an autoigniting jet of ethylene fuel. Direct Numerical Simulation by E.S.Richardson, C.Yoo, R.Sankaran, and J.H.Chen,

2 Modelling of turbulent reacting flows 2 Development of modelling framework for including detailed small-scale physics in reacting flow models. “Advanced modelling for two-phase reacting flow” (EPSRC fellowship ) Understanding and validation through high- fidelity simulation: Multi-component single droplet evaporation Turbulent combustion DNS – stratified & partially premixed. Multi-component spray combustion (Lagrangian spray ‘DNS’). Analysis of resolved evaporating spray (Demoulin 2011). Fundamental numerical experiments Practical modelling for real applications

3 Wider applications 3 Dynamic modelling of engines and power systems: Advanced engine concepts with Liquid Nitrogen injection. Combined-cycle (micro) power systems. Modelling statistical interactions and uncertainty propagation: Air quality modelling Plug-in Hybrid Electrical Vehicle charging
