Cerfacs Enter the world of high performance ...

NEWS

ISAF project : To accelerate the transition to SAFs, SAFRAN and CERFACS have together obtained an allocation of 44 million CPU hours on the LUMI-C super-computer as part of the EuroHPC Regular Access call in November 2022.

CERFACS |  11 March 2023

The objective of the ISAF project is to study the impact of SAFs (Sustainable Aviation Fuels) on engine operation and pollutant emissions, using high-fidelity Large Eddy Simulations (LES). The methodology developed at CERFACS combines Analytically Reduced Chemistry (ARC) with a multi-component evaporation model to capture the effect of fuel. The target configurations range from academic burners (CRSB at CORIA, SSB at DLR Stuttgart), to isolated industrial injection systems (MICADO at ONERA, HERON at CORIA) and complete annular combustor configurations (BEARCAT at SAFRAN, NTNU test bench).Read more

This is here applied to derive a two-step scheme for kerosene flames at reheat conditions typical of aircraft engines for Large Eddy Simulations applications. It comprises 6 species (kerosene, , , , , ) and two reactions where only two kinetic constants are adjusted: the pre-exponential constant of the reactions are changed as a function of the progress variable and equivalence ratio in order to match both auto-ignition times and premixed flame speeds in rich conditions. Vitiation levels are taken into account through the equivalence ratio characterizing the oxidizer stream composition in the reheat combustor. The novel two-step scheme is validated against semi-detailed chemistry for 1D laminar kerosene/vitiated air flames with decreasing inlet velocity (thereby decreasing reactant residence time) changing from auto-igniting flames at high inlet velocities to propagating flames flashing back at low inlet velocities. The scheme is proved to capture auto-igniting as well as propagating flames found in afterburner conditions at very low computational cost and with a precision comparable to complex chemical schemes.}}
