Correction: The role of cross thermal buoyancy on flow transition around side-by-side cylinders at low Reynolds numbers

Aerodynamic loads on cactus-shaped cylinders at low Reynolds numbers

Direct numerical simulations of flow past cactus-shaped cylinders are performed at Reynolds numbers of 20, 100, and 300. The results are contrasted to those from smooth cylinders at the same Reynolds numbers. The cavities in the cactus-shaped cylinders are seen to reduce the forces acting on them. At Reynolds number of 20, the drag is reduced by 22% due to reduction in the viscous forces. At Re...

Flow Instability around a 2d Airfoil Induced by Acoustic Disturbances at Low Reynolds Numbers

In this paper, a numerical study is presented to investigate a boundary-layer instability on the suction side of a NACA0006 airfoil, induced by aerodynamic sound scattered from a trailingedge. By incorporating a linear stability analysis into the direct simulations with a compressible Navier-Stokes code using high-order accurate schemes, the unsteady characteristics are estimated upon resolving...

Transition of planar Couette flow at infinite Reynolds numbers.

An outline of the state space of planar Couette flow at high Reynolds numbers (Re<10^{5}) is investigated via a variety of efficient numerical techniques. It is verified from nonlinear analysis that the lower branch of the hairpin vortex state (HVS) asymptotically approaches the primary (laminar) state with increasing Re. It is also predicted that the lower branch of the HVS at high Re belongs ...
