![]() ![]() It is found that the detailed chemistry case with clustering can reproduce nearly identical results to detailed chemistry without any acceleration if CO is added as a clustering variable. ![]() Then, computational costs are assessed by comparing the performance and scalability of the simulations with each of the combustion models. A comparison of results with and without chemistry acceleration techniques for detailed chemistry is included. To fully capture potential emissions, a soot moment model, and Zeldovich NOx model are employed along with radiation. Comparisons for NOx, CO, Unburned Hydrocarbons, and Soot are made, along with the radial temperature profile. The objective of this work is to investigate the ability of FGM and detailed chemistry modeling to capture pollutant formation in an aero-engine combustor. Both take advantage of a hybrid chemical mechanism (H圜hem) which has previously demonstrated very good accuracy for real fuels such as Jet-A with only 47 species. This work presents Large Eddy Simulation (LES) results using both the Flamelet Generated Manifold (FGM) and detailed chemistry combustion models. A Honeywell liquid-fueled gas turbine test combustor, at idle conditions is numerically investigated in Simcenter STAR-CCM+ version 2020.3. ![]()
