CDP: Unstructured LES Code
The objective of the LES group is to develop numerical methods and physical models to predict the reacting multiphase flow in a jet engine combustor. In the combustor, pressurized air from the upstream compressor is reacted with atomized liquid fuel to produce the combustion products that drive the downstream turbine. The Large Eddy Simulation (LES) approach is used to simulate the combustor because of its demonstrated superiority in predicting turbulent mixing when compared to the Reynolds Averaged Navier-Stokes (RANS) technique.
The LES group is developing CDP, CITS unstructured mesh LES code. The major challenges are:
- Develop algorithms to perform accurate LES calculations on unstructured meshes in complex geometries
- Develop advanced combustion models for predictive the reactive flow inside jet engine combustors
- Develop models to simulate liquid fuel atomization and gas/liquid interactions
