Both third-order and fourth-order SD methods
are used on unstructured quadrilateral grids. The vortex shedding pattern of an airfoil
in an oscillating plunge motion becomes asymmetric at a su±cientl...
Scale-adaptive simulation of flow past wavy cylinders at a subcritical Reynolds number
Wavy cylinders Drag reduction Vortex shedding Vibration control SAS
2012/2/29
The Xu {&} Yan scale-adaptive simulation (XY-SAS) model is employed to simulate the flows past wavy cylinders at Reynolds number 8\times 10^3 . This approach yields results in good agreement with expe...
Numerical simulation of flow past a cylinder in orbital motion
circular cylinder lock-in orbital motion vortex shedding unsteady flow
2010/3/12
A finite di®erence solution is presented for 2D laminar unsteady flow around a circular cylinder in orbital motion placed in a uniform flow for Re = 130, 160, and 180. Four cases displaying full l...
