Large-Eddy Simulation: Current Capabilities, Recommended Practices, and Future Research (2009, methodology): “More recently, the partially averaged Navier–Stokes (PANS) method has been proposed by Girimaji [36], in which a single turbulence model is used, and whether the model is serving as a RANS closure, subgrid-scale model, or somewhere in between is determined by the level of grid resolution and a const”
Numerical analysis of unsteady cavitating turbulent flow and shedding horse-shoe vortex structure around a twisted hydrofoil (2013, methodology): “Girimaji (2006) noted that the PANS equations are identical to the RANS equations, but with different model coefﬁcients, which enables the PANS model to be easily implemented into computational ﬂuid dynamics (CFD) codes without any signiﬁcant changes.”
Hybrid LES/RANS methods for the simulation of turbulent flows (2008, methodology): “With the specific models proposed in [117], the Kt and et equations become formally identical to the original RANS closure.”
Turbulence Modeling in the Age of Data (2018, background): “ and widespread across dierent industries. Among these, RANS (Reynolds Averaged Navier-Stokes) and LES (Large Eddy Simulation) approaches are the most common, although there exist many alternatives (Girimaji 2006; Spalart 2009). RANS techniques rely completely on modeling assumptions to represent tu”
