Improved version of LeMoS hybrid model for ambiguous grid densities
International Journal of Naval Architecture and Ocean Engineering, 2018 Application of the LeMoS hybrid (LH) URANS/LES method for the wake parameters prediction is considered. The wake fraction coefficient is calculated for inland ship model M1926 under shallow water conditions and compared to results of PIV measurements. It

Impact of Porous Media on Boundary Layer Turbulence
Fluids, 2022 The subsonic flows around NACA 0012 aerofoils with a solid, a porous, and a poro-serrated trailing edge (TE) at a Reynolds number of 1 × 106 are investigated by a hybrid Reynolds-averaged Navier–Stokes (RANS)/large-eddy simulation (LES) approach.

Hybrid RANS/LES of plane jets impinging on a flat plate at small nozzle-plate distances
Archives of Mechanics, 2013 A k-ω based hybrid RANS/LES (Reynolds-averaged Navier-Stokes/large eddy simulation) model is tested for simulation of plane impinging jets at various nozzle-plate distances (H/B, where H is the distance and B is the slot's width) and various Reynolds ...

A Hybrid-Filter Approach to Turbulence Simulation [PDF]
, 2010 Germano (Theor Comput Fluid Dyn 17:225–331, 2004) proposed a hybrid-filter approach, which additively combines an LES-like filter operator (F) and a RANS-like statistical operator (E) using a blending function k: H = kF + (1 − k)E.

On Interface Issues in LES/RANS Coupling Strategies: A Method for Turbulence Forcing
Journal of Fluid Science and Technology, 2011 The present work deals with a computational strategy coupling near-wall, eddyviscosity-based RANS models with LES within a zonal Hybrid LES/RANS (HLR) framework. Key questions concerning the coupling of both methods, the inherently steady RANS method and
