Abstract:

The atomization of liquid fuels is a key process in gas turbine engines and augmentors, directly influencing combustion and thus engine performance. While adequate models exist for the secondary atomization, the crucial initial breakup is not well understood and predictive numerical simulation tools to analyze the process in detail do not exist. In this project, we propose to apply the recently developed Refined Level Set Grid (RLSG) to the primary atomization problem. This method, in a detached code, resolves and tracks all relevant phase interface length scales on a separate, locally refined grid. The RLSG code is coupled to the flow solver via a multi-code coupling environment, thereby ensuring easy portability and expandability. The resulting software package has been successfully applied to several two-phase flow benchmarks and is able to predict the observed physical breakup mechanisms during coaxial atomization. In the project's initial phase, we will access the capability of the proposed software framework to predict the atomization of liquid jets in cross-flow under conditions relevant to gas turbines and augmentors using experimental data in the near- and far-field. The data will then be assessed for its suitability to derive Large Eddy Simulation models for primary atomization.
