Hidden mechanism of dynamic large-eddy simulation models
Xiaohan Hu, Keshav Vedula, George Ilhwan Park
The dynamic model is one of the most successful inventions in subgrid-scale (SGS) modeling as it alleviates many drawbacks of the static coefficient SGS stress models. The model co…
Revisiting Crossflow-Based Stabilization in Channel Flows
Muhammad Abdullah, George Ilhwan Park
Stabilization schemes in wall-bounded flows often invoke fluid transpiration through porous boundaries. While these have been extensively validated for external flows, their effica…
Physics-based distinction of nonequilibrium effects in near-wall modeling of turbulent separation bubble with and without sweep
Imran Hayat, George Ilhwan Park
Pressure-gradient-induced separation of swept and unswept turbulent boundary layers, based on the DNS studies of Coleman et al. (J. Fluid Mech. 2018 & 2019), have been analyzed for…
Linear Stability Analysis of Oblique Couette-Poiseuille flows
Muhammad Abdullah, George Ilhwan Park
We perform a detailed numerical study of modal and non-modal stability in oblique Couette-Poiseuille profiles, which are among the simplest examples of three-dimensional boundary l…
Large-eddy simulation of separated flows on unconventionally coarse grids
Yuanwei Bin, George I. Park, Yu Lv +1
We examine and benchmark the emerging idea of applying the large-eddy simulation (LES) formalism to unconventionally coarse grids where RANS would be considered more appropriate at…
A priori screening of data-enabled turbulence models
Peng E S Chen, Yuanwei Bin, Xiang I A Yang +3
Assessing the compliance of a white-box turbulence model with known turbulent knowledge is straightforward. It enables users to screen conventional turbulence models and identify a…
