Numerical Modelling

Direct Numerical Simulation of a hydrogen reheat flame stabilized by autoignition in a model sequential combustor (SINTEF/Sandia NL)

The development of the sequential combustion system to achieve 100% hydrogen operation at H-class conditions will be supported by advanced numerical modelling and simulations. These activities will combine state-of-the-art modelling tools for the simulation of turbulent reactive flows and the computational power of modern high-performance computers. High-resolution calculations of both combustor stages will reveal detailed insights and trends about flame stabilisation and emission formation in each stage. Additionally, a reduced-order model of both stages will be constructed to investigate their interaction and map the boundaries of their stability. The numerical results will be used to design the combustion system, with the aim of reducing combustion testing costs and improving the operational window, specifically regarding fuels containing up to 100% H2.
