Abstract: The complex geometry of the aero-engine combustion chambers and the strong nonlinear interaction between turbulence and chemical reactions require high precision characterization of the flow, combustion, and their interaction with high space-time resolution. Currently, the difficulty in numerical simulation of turbulent combustion in the combustion chamber remains one of the bottleneck problems. This article will introduce the main algorithm of the AECSC-JASMIN software, which is jointly developed by the Aeroengine Numerical Simulation Research Center of Beihang University, Institute of Applied Physics and Computational Mathematics, and CAEP Software Center for High-Performance Numerical Simulation, as well as the example verification of the software. It will be tested with Sandia`s jet flame, concave strut flame-holder, and single-head combustion chamber. Compared with the experimental data, the prediction results of the jet and concave strut flame-holder are consistent with the experimental values, with an average relative error within 15%. The simulation results of the single-head combustion chamber conform to the physical reality, and the total pressure loss is consistent with the experimental value. Therefore, AECSC-JASMIN software can be used for numerical simulation of high-resolution and high-precision turbulent combustion in complex structures.
