Advanced Chemical Modeling for Turbulent Combustion Simulations
Abstract
The goals of this project were the development of new sub-filter models for large eddy simulation of turbulent combustion and of chemical mechanisms for jet fuel surrogates. The sub-filter modeling work focuses on the development of a framework for describing multiple combustion regimes using the flamelet approach, on describing the scalar dissipation rate in turbulent non-premixed combustion, and on modeling strain effects in turbulent premixed combustion. The chemistry work proposes a method for defining jet fuel surrogates, describes how different sub-mechanisms can be incorporated into the definition, and finally creates and validates a mechanism that serves as an accurate surrogate for jet fuel behavior.
