Abstract (Italiano)
The topology of the steady three-dimensional flow is investigated in a partially liquid-filled horizontal rotating cylindrical drum. The drum is infinity long in its axis direction and it is rotating about its axis. A steady cellular flow arise due to introducing an infinitesimal perturbation and Lagrangian chaos is demonstrated for supercritical Reynolds numbers. The topological analysis is done in order to see the Kolmogorov-Arnold-Moser tori for three Reynolds numbers. This work is conducted by simulating numerically the incompressible Navier-Stokes equations through OpenFOAM.
