Dimensional Decomposition of Turbulent Reacting Flows
A dimensional-decomposition approach, decomposing 3D into 3×1D for turbulent (reacting) flows are motivated, discussed and investigated. In the three-dimensional Linear Eddy Model (LEM3D), three orthogonally intersecting arrays of 1D domains are coupled to capture the 3D characteristics of fluid...
A Parametric Study of LEM3D Based on Comparison with a Turbulent Lifted Hydrogen Jet Flame in a Vitiated Co-Flow
A novel model, the hybrid RANS-LEM3D model, is applied to a lifted turbulent N 2 diluted hydrogen jet flame in a vitiated co-flow of hot products from lean H 2 /air combustion. In the present modeling approach, mean-flow information from RANS provides model input to LEM3D, which returns the scalar...
Three-dimensional Linear Eddy Modeling of a Turbulent Lifted Hydrogen Jet Flame in a Vitiated Co-flow
A new methodology for modeling and simulation of reactive flows is reported in which a 3D formulation of the Linear Eddy Model (LEM3D) is used as a post-processing tool for an initial RANS simulation. In this hybrid approach, LEM3D complements RANS with unsteadiness and small-scale resolution in a...
