Phase-Averaged Analysis of Three-Dimensional Vorticity in the Wake of Two Yawed Side-By-Side Circular Cylinders
Thewake flow behind two yawed side-by-sidecircular cylinders is investigated using athree-dimensional vorticity probe. Four yaw angles (α), namely, 0°, 15°, 30° and 45° and twocylinder spacing ratios T of 1.7 and 3.0 were tested. For T = 3.0, there exist two vortex streets and the cylinders behave as independent and isolated ones. The maximum contour value of the coherent streamwise vorticity *...
متن کاملNumerical simulation of three-dimensional flow around two circular cylinders in tandem arrangement
Three-dimensional fluid flow around two circular cylinders in tandem arrangement is computed by the finite difference method without a turbulence model. The overlapped grid technique is employed to catch the flow interference between the two tandem cylinders. It is confirmed that the abrupt numerical change of drag coefficients and the Strouhal number is in good agreement with the previous expe...
متن کاملFlow past two tandem circular cylinders using Spectral element method
In this paper, flow past around two circular cylinders which are tandem arranged at a Reynolds number of 200 is numerically investigated by spectral element method. To validate the numerical method for incompressible Navier–Stokes equations, the benchmark problem of flow over a single circular cylinder is employed, with the numerical results in a good agreement with the available literatures. T...
متن کاملLes around Two Cylinders in Tandem
The flow around an arrangement of two-in-tandem cylinders exhibits a remarkably complex behaviour that is of interest for many engineering problems, such as environmental flows or structural design. In the present paper, a Large Eddy Simulation using a staggered Cartesian grid has been performed for the flow around two-in-tandem cylinders of diameter D=20mm and height H=50mm submerged in an ope...
متن کاملComputation of Flow Behind Three Side-by-Side Cylinders of Unequal/Equal Spacing
This paper aims to simulate unstable gap flows of three side-by-side cylinders unequally/equally spaced at T1/d = 1.5 and T2/d = 1.6 in a uniform cross flow (Re=300). The simulation is carried out using ANSYS Flotran 7.0. A mesh-independent study is conducted on a single cylinder at Re=100. The Strouhal number and wake flow characteristics compare well with experimental results. Simulation of t...
