A fuel mapping strategy for unsteady injection processes within the representative interactive linear eddy model (RILEM)

This paper presents a fuel mapping strategy for a new regime-independent combustion modeling strategy for non-premixed combustion in which the linear eddy model (LEM) is used as a representative interactive regimeindependent turbulent combustion model coupled to a 3D CFD solver. Parameters and boundary conditions that determine the evolution of the LEM are supplied by the 3D CFD calculation and updated at each time step. The LEM is then solved for the corresponding time step, providing the 3D CFD code with an updated composition state. This initialization strategy for this new representative interactive linear eddy model (RILEM) is tested by simulations of an n-heptane spray, demonstrating the ability of the RILEM to describe spray combustion processes
