Honeywell Engines, Systems & Services has developed the Advanced Combustion Tool (ACT) CFD process to rapidly analyze the performance of a combustor configuration from a given fuel injector, CAD geometry and engine cycle information. ACT integrates and streamlines the traditional steps of generating and specifying geometry, mesh, physical models, boundary conditions, initial conditions, convergence criteria and post-processing. Notably, ACT utilizes several key features to reduce cycle time and improve fidelity in the CFD analysis process: a high-pressure spray diagnostic facility to obtain fuel droplet boundary conditions, feature-based macros to parametrically automate geometry and mesh generation, preprocessors to simplify and standardize boundary condition and physical model specification, and post-processors to provide graphical and analytical responses. This integrated process for CFD modeling and optimization is the subject of this paper. A demonstration of this process is the numerical prediction of the TFE731-60 combustor flowfield on a 30 degree sector model compared to experimentally measured results.
