Advanced Lattice-Boltzmann Combustion Modelling – MALBEC

Submission summary

The objective is to carry out the first 3D simulation of a turbulent, carbon-free hydrogen-air flame, using Lattice-Boltzmann methods. Our latest results indicate that such method should lead to speed-up close to 80-90% compared to classical Navier-Stokes based solvers. Such speed-up corresponds to an order of magnitude and would constitute a significant technological breakthrough, should the method be applied to complex configurations. It would provide us with a new efficient method of better understanding H2 safety related questions, as well as the physics of deflagration. In addition, such gain would diminish the ecological footprint associated to classical combustion chambers development, largely relying on numerical simulation.
