ABSTRACT
The state of the art in multi-dimensional combustor modeling, as evidenced by the level of sophistication employed in terms of modeling and numerical accuracy considerations, is also dictated by the available computer memory and turnaround times afforded by present-day computers. With the aim of advancing the current multi-dimensional computational tools used in the design of advanced technology combustors, a solution procedure is developed that combines the novelty of the coupled CFD/spray/scalar Monte Carlo PDF (Probability Density Function) computations on unstructured grids with the ability to run on parallel architectures. In this approach, the mean gas-phase velocity and turbulence fields are determined from the solution of a conventional CFD method, the scalar fields of species and enthalpy from a modeled PDF transport equation using a Monte Carlo method, and a Lagrangian-based dilute spray model is used for the liquid-phase representation.
