General-purpose Data-driven Wall Model for Low-speed Flows Part I: Baseline Model
Yuenong Ling, Imran Hayat, Konrad Goc +1
We present a general-purpose wall model for large-eddy simulation. The model builds on the building-block flow principle, leveraging essential physics from simple flows to train a…
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…
Reference map technique for Lagrangian exploration of coherent structures
Imran Hayat, Ryan T. Black, George Ilhwan Park
We explore the application of the reference map technique, originally developed for the Eulerian simulation of solid mechanics, in Lagrangian kinematics of fluid flows. Unlike trad…
Wall-modeled large-eddy simulation of three-dimensional turbulent boundary layer in a bent square duct
Xiaohan Hu, Imran Hayat, George Ilhwan Park
We conduct wall-modeled LES (WMLES) of a pressure-driven three-dimensional turbulent boundary layer (3DTBL) developing on the floor of a bent square duct to investigate the predict…
Implementation and performance analysis of efficient grid-free integral wall models in unstructured-grid LES solvers
Imran Hayat, George Ilhwan Park
Two zonal wall models based on integral form of the boundary layer differential equations, albeit with algebraic complexity, have been implemented in an unstructured-grid cell-cent…
