Highly resolved large-eddy simulation of separated flow in a channel with streamwise periodic constrictions
TL;DR: In this article, a large-eddy simulation is used to investigate the mean and turbulence properties of a separated flow in a channel constricted by periodically distributed hill-shaped protrusions on one wall.

Wall-Modeled Large-Eddy Simulation for Complex Turbulent Flows
Sanjeeb Bose,George Ilhwan Park +1 more
TL;DR: This work reviews recent investigations in wall-modeled LES, including the development of novel approximate boundary conditions and the application of wall models to complex flows (e.g., boundary-layer separation, shock/boundary-layer interactions, transition).
Journal ArticleDOI
Flow over periodic hills – Numerical and experimental study in a wide range of Reynolds numbers
TL;DR: In this article, a detailed analysis of the flow over smoothly contoured constrictions in a plane channel is presented, which is a generic case of a flow separating from a curved surface with well-defined flow conditions.

Investigation of wall-function approximations and subgrid-scale models in large eddy simulation of separated flow in a channel with streamwise periodic constrictions
TL;DR: In this paper, large eddy simulations are presented for the flow in a periodic channel segment, which is laterally constricted by hill-shaped obstructions on one wall, having a height of 33% of the unconstricted channel.

Second-moment closure: present… and future?
TL;DR: In this paper, the authors summarized the present position of second-moment closure and outlined possible directions for future development, and the desirability of introducing a further second-rank tensor into the closure is considered; the conclusion reached is that, for most applications, the likely benefits would not justify the additional effort.
Second-moment closure: Present ... and future?
TL;DR: A simple form of second-moment treatment that has been widely used for computing industrial flows gives demonstrably superior predictive accuracy that any eddy—viscosity model, and the introduction of a second scale-related equation is arguably a more sensible approach.
Effects of Streamline Curvature on Turbulent Flow.
TL;DR: A review of current knowledge, a discussion of methods of predicting curvature effects, and a presentation of principles for the guidance of future workers can be found in this article, along with a progress report.
