Non-equilibrium wall model for large eddy simulations of complex flows exhibiting turbulent smooth body separation
Rahul Agrawal, Sanjeeb T. Bose, Parviz Moin
In this work, a non-equilibrium wall model is proposed for the prediction of turbulent flows experiencing adverse pressure gradients, including separated flow regimes. The mean-flo…
Studies of Transonic Aircraft Flows and Prediction of Initial Buffet Onset Using Large-Eddy Simulations
Konrad A. Goc, Rahul Agrawal, Sanjeeb T. Bose +1
This article utilizes the Large-Eddy Simulation (LES) paradigm with a physics-based turbulence modeling approach, including a dynamic subgrid-scale model and an equilibrium wall mo…
Are the dynamics of wall turbulence in minimal channels and larger domain channels equivalent? A graph-theoretic approach
Ahmed Elnahhas, Emma Lenz, Parviz Moin +2
This work proposes two algorithmic approaches to extract critical dynamical mechanisms in wall-bounded turbulence with minimum human bias. In both approaches, multiple types of coh…
Reynolds number dependence of length scales governing turbulent flow separation with application to wall-modeled large-eddy simulations
Rahul Agrawal, Sanjeeb Bose, Parviz Moin
This article proposes a Reynolds number scaling of the required grid points to perform wall-modeled LES of turbulent flows encountering separation off a solid surface. Based on com…
An extension of Thwaites method for turbulent boundary layers
Rahul Agrawal, Sanjeeb T. Bose, Kevin P. Griffin +1
Thwaites (1949) developed an approximate method for determining the evolution of laminar boundary layers. The approximation follows from an assumption that the growth of a laminar…
Large-eddy simulations of the NACA23012 airfoil with laser-scanned ice shapes
Brett Bornhoft, Suhas S. Jain, Konrad Goc +2
In this study, five ice shapes generated at NASA Glenn's Icing Research Tunnel (IRT) are simulated at multiple angles of attack (Broeren et al., J. of Aircraft, 2018). These geomet…
