Abstract:

The computational fluid dynamics (CFD) simulation is gaining attraction in the development of modern unmanned aerial vehicles (UAV), but few research has been made on quadcopters and the characterization of the flows generated by the propellers, which determine the thrust capacity. Therefore, the purpose of this study is to assess the performance in the 3D flow simulation of the most promising methods: multiple reference frames (MRF) and sliding meshes. The impact of the ground's proximity has also been taken into consideration. Even though there was a clear difference in the measurement of thrust, the results for a single propeller showed that both models were similar in terms of assessing the ground effect. This study examines the effects of steady wind conditions on a quadcopter's capacity to maintain a hovering scenario using computational fluid dynamics (CFD). To evaluate study parameters, preliminary isolated rotor simulations are run using the Improved Delayed Detached Eddy Simulation turbulence model. The mesh that will be utilized in full scale simulations is chosen after spectral analysis has evaluated the meshes of the isolated rotor.
