Article Preview

Flow over circular cylinder at Reynolds number 3900 is studied numerically using the technique of Large Eddy Simulation .As a result, strong three-dimensional characteristics are revealed in flow around a cylinder at Re=3900. As spanwise and streamwise mesh refinement is done respectively, result improves similarly. But the CPU time consumed is too much when refinement meshes are used. Also the simulation result with Smagorinsky subgrid-scale model is investigated to be better than subgrid-scale k model.
