Scientists of the RWTH Aachen University have carried out a peta-scale direct numerical simulation (DNS) of a temporally evolving lean premixed methane/air jet flame. The DNS is intented to closely mimic gas turbine combustion and can be regarded as an idealized representation of a premixed flame element inside a jet burner. To realize high resolution of flame and turbulence and to obtain converged statistics, the simulation domain was discretized with almost three billion grid points which together with the chemistry model resulted in nearly 100 billion degrees of freedom.
