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 s...

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 c...

The LEM3D stochastic model for numerical simulation of turbulent mixing is used to simulate differential molecular diffusion effects in an isothermal jet of hydrogen and Freon 22 issued into air. The computations are compared with a published experimental study of the flow configuration. Salient fea...
