Computer hardware is fundamentally changing, with performance now coming from parallelism, rather than increasing clock frequency. Current combustion codes will not perform well on evolving hardware without a major re-working of algorithms and implementation.
NREL is playing a key role in developing an exascale computing simulation framework for modeling multiphysics reacting flows for combustion applications. This simulation capability will enable unique first-principles and near-first principles simulations of mixing, spray vaporization, auto-ignition, flame propagation, and soot/radiation in conditions relevant to practical combustion devices.
The exascale combustion simulation framework offers a tremendous opportunity for advancing design technology for energy generation and propulsion.
