Coupling Turbulence in Hybrid LES-RANS Techniques [PDF]
, 2011 A formulation is proposed for hybrid LES-RANS computations that permits accurate computations during resolution changes, so that resolution may be changed at will in order to employ only as much resolution in each subdomain as is required by the physics.

Hybrid RANS/LES of round impinging jets
Journal of Physics: Conference Series, 2011 Fluid flow and heat transfer characteristics are presented for simulations of round impinging jets at two nozzle-plate distances H/D = 2 and 10 (D is the nozzle exit diameter) and two Reynolds numbers Re = 5000 and 70,000 with hybrid RANS/LES (Reynolds-averaged Navier-Stokes/Large Eddy Simulation), dynamic Smagorinsky LES and RANS k−ω models. Three k−ω
