Cylinder flow 3900
Web摘要： The effects of numerical viscosity, subgrid scale (SGS) viscosity and grid resolution are investigated in LES and VMS-LES simulations of the flow around a circular cylinder at Re = 3900 on unstructured grids. WebSome typical and characteristic physical quantities, such as the drag coefficient, the root-mean-square lift fluctuations, the Strouhal number, the pressure and skin friction distributions around the cylinder, etc.are calculated and compared with previously reported experimental data, finer-grid large-eddy simulation (LES) data and those obtained …

WebDec 23, 2014 · It is well known that the flow past a circular cylinder at critical Reynolds number combines flow separation, turbulence transition, reattachment of the flow, and further turbulent separation of the boundary layer. WebThe experiment used two sets of cylinders. The first set was designed to study heat transfer; hollow cylinders of 66 mm diameter and 0.1 mm thickness are made of steel sheets. The model’s structure is shown in Figure 1. Figure 1. Cylinder structure.
