Abstract

We report on Large-eddy simulations (LES) of a flow around a cylinder in a narrow duct channel at the Reynolds number of 2 000, 3 000 based on the bulk velocity and diameter of the cylinder. We investigate a mechanism of the transition occurring from steady laminar flow at Re = 2 000 to turbulent flow at Re = 3 000 with attached recirculation zone and thin sinusoidal far wake.
