Computational methods for turbulent reacting flows in the chemical process industry
Turbulent reacting flow modeling is complicated by the fact that these flows contain a wide range of time and length scales. In order to formulate acceptable computational fluid dynamic algorithms for reacting flows, there must be an understanding of the complex interactions between turbulence, molecular diffusion and chemical kinetics. The relative importance of specific modeling steps depend strongly on the type of flow under consideration. In this paper, single-phase, constant-density flows with constant viscosity and equal diffusivities are considered and the emphasis is on modeling the interactions between turbulent mixing and chemical reactions in on-premixed turbulent reacting flows.
