On modeling of a small UAV’s propeller for CFD simulation in low Reynolds numbers

Abstract

While there are many studies related to propeller in high turbulent environment conditions, the studies on propeller at low Reynold for model aircraft or UAV get little attention. However there are many propeller is used for this condition. In this article, we will build simulation process for propeller in conditions of below 100,000 Reynold and rotating speed lower than 10,000 rpm. The propeller geometry is created in computer based on real propeller properties at sections at 75% propeller blade length.  OpenFOAM, an opened source software, is used. The simulation results were compared with experimental data to verify
