Abstract
The applications of UAVs (Unmanned Air Vehicles) are expanding in various industries, particularly in defense and agriculture. As an emerging technology, numerous studies have been conducted to examine different aspects of UAVs. This study aims to investigate the effects of different propeller geometries on UAV performance, with a focus on comparing a conventional propeller and a toroidal propeller. For the analysis of the toroidal propeller, Computational Fluid Dynamics (CFD) serves as a valuable tool to predict flow behavior, pressure, and flow rate. Significant effort has been made to predict flow behavior efficiency, primarily using the Reynolds-averaged Navier-Stokes (RANS) approach, which several studies have identified as the most effective method. To achieve this objective, numerical simulations will be performed using the Multi Reference Frame (MRF) method to simulate the motion forces generated by the propeller in the airflow. Initial results indicate that the optimal meshing approach involves a total of 1,750,320 cells.
