Combustor Simulation for Low Emissions and High Reliability

Combustor simulation is an essential element of the gas turbine and aircraft engine design process. It starts with aerodynamic simulation to accurately determine flow splits, pressure drops, mixing and cooling. High-fidelity combustion simulation is required to determine temperatures, combustion patterns, flame position, products of combustion, outlet pattern factor as well as provide a detailed emissions prediction. Geometries are complex and mesh size may be very large, particularly for Large Eddy Simulation (LES) cases.

Detailed fuel libraries and reaction mechanisms are now available for the highest fidelity and accuracy of simulation.
