Simulation of the flow around a circular cylinder at Re=3900 with Partially-Averaged Navier-Stokes equations
TL;DR: In this article, the authors employed partially-averaged Navier-Stokes (PANS) equations to simulate the flow around a smooth circular cylinder at Reynolds number 3900 and evaluated the importance of discretization and modelling errors on the accuracy of this mathematical model.

Comparative assessment of PANS and DES for simulation of flow past a circular cylinder
TL;DR: In this paper, a partially-averaged Navier-Stokes (PANS) method and detached eddy simulation (DES) were evaluated for the simulation of unsteady turbulent flows and the model performance was assessed by a detailed comparison of PANS predictions to the corresponding experimental data and DES results.

On the simulation of the flow around a circular cylinder at Re=140,000
TL;DR: In this paper, the authors compared the performance of different RANS and Scale-Resolving Simulation (SRS) methods to simulate the upper limit of the flow regime, where turbulent transition occurs in the free shear-layers.

The PANS k–ε model in a zonal hybrid RANS–LES formulation
TL;DR: In this paper, a hybrid RANS-LES model is proposed for fully developed channel flow and embedded LES in a hump flow, which yields virtually grid-independent flow fields and turbulent viscosities.

Vortex Dynamics in the Cylinder Wake
TL;DR: A review of wake vortex dynamics can be found in this article, with a focus on the three-dimensional aspects of nominally two-dimensional wake flows, as well as the discovery of several new phenomena in wakes.

Turbulence - The filtering approach
TL;DR: In this paper, a new operatorial approach to the study of turbulence is described, based on the general algebraic properties of the filtered representations of a turbulence field at different levels.

An experimental study of entrainment and transport in the turbulent near wake of a circular cylinder
Brian J. Cantwell,Donald Coles +1 more
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.
