Strategies for turbulence modelling and simulations
TL;DR: In this paper, the authors discuss the many levels possible for the numerical prediction of a turbulent flow, the target being a complete airplane, turbine, or car, and their hope is to stimulate reflection, discussion, and planning.

Detached-Eddy Simulations past a circular cylinder
TL;DR: In this paper, the authors used the Detached-Eddy Simulation (DES) technique for smooth surface separation with laminar separation (LS) and turbulent separation (TS) at Reynolds numbers 50,000 and 140,000.

Numerical simulation of the flow around a circular cylinder at high Reynolds numbers
TL;DR: In this article, the viability and accuracy of large-eddy simulation with wall modeling for high Reynolds number complex turbulent flows is investigated by considering the flow around a circular cylinder in the supercritical regime.

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.

A proposed modification of the Germano subgrid‐scale closure method
TL;DR: In this paper, the subgrid-scale closure method developed by Germano et al. is modified by use of a least squares technique to minimize the difference between the closure assumption and the resolved stresses.

TL;DR: In this paper, an experimental investigation of transport processes in the near wake of a circular cylinder at a Reynolds number of 140000 was performed using X-array hot-wire probes mounted on a pair of whirling arms, which increases the relative velocity component along the probe axis and decreases the relative flow angle to usable values in regions where fluctuations in flow velocity and direction are large.

Distribution of local pressure and skin friction around a circular cylinder in cross-flow up to Re = 5 × 10 6
TL;DR: In this paper, the authors measured the local pressure and skin friction distribution around a cylinder and calculated the total drag, the pressure drag and the friction drag, which can be used to define three states of the flow: the subcritical flow, where the boundary layer separates laminarly; the critical flow, in which a separation bubble, followed by a turbulent reattachment, occurs; and the supercritical flow where an immediate transition from the laminars to the turbulent boundary layer is observed at a critical distance from the stagnation point.
