A critical review on the simulations of wind turbine aerodynamics focusing on hybrid RANS-LES methods
TL;DR: The hybrid RANS-LES method (HRLM) as mentioned in this paper is a technique to bridge the gap between less accurate RANS and more computational costly LES method, which is a remedy to turbine aerodynamics in complex flow conditions.

A new inflow turbulence generator for large eddy simulation evaluation of wind effects on a standard high-rise building
TL;DR: In this paper, a narrowband synthesis random flow generator (NSRFG) was proposed for large eddy simulation of atmospheric boundary layer (ABLBP) flow. And the new technique was then applied to the numerical simulation of the turbulent flow around the CAARC standard building model, which was tested in the boundary layer wind tunnel of the South China University of Technology.

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.

A dynamic subgrid‐scale eddy viscosity model
TL;DR: In this article, a new eddy viscosity model is presented which alleviates many of the drawbacks of the existing subgrid-scale stress models, such as the inability to represent correctly with a single universal constant different turbulent fields in rotating or sheared flows, near solid walls, or in transitional regimes.
