概要

• 論文の詳細を見る

• In this study, the Large Eddy Simulation with the G-equation model is performed in the geometry of an axially staged annular combustor of a gas turbine engine. The propagation of flames in the turbulent flow field depending on the equivalence ratios is represented by the extended G-equation model. The predicted results in the geometries of an experimental test piece and the modeled whole combustor are compared with each other, and are discussed using experimental data.
