Rotors form an integral part of many flow machines, e.g. propellers, helicopters, wind turbines, turbo-machinery, etc. Although many computational models (differing in complexity and starting assumptions) for the estimation of their aerodynamic properties exist, accurately simulating flows around rotors still presents a challenge (due to unsteadiness, turbulence, flow separation, and other flow phenomena). This presentation will focus on some of the commonly most employed computational approaches and present some of the most characteristic quantitative and qualitative results obtained for a small-scale rotor designed at the University of Belgrade, Faculty of Mechanical Engineering including a background story about the blade design. Most important conclusions and recommendations shall be provided. Also, a brief summary of the latest work performed at the Department of Aeronautics shall be given.
