Description
Description
In this study, a comprehensive acoustic simulation of a quadcopter was performed using ANSYS Fluent, a powerful computational fluid dynamics (CFD) software. The primary objective was to investigate the noise generated by the quadcopter during operation and to gain insights into its acoustic characteristics.
The quadcopter geometry was designed using SpaceClaim, a 3D modeling software integrated with ANSYS. Leveraging the symmetry of the quadcopter, a 3D symmetric model was created, which significantly reduced the computational cost while maintaining the accuracy of the simulation. The designed geometry captured the essential features of the quadcopter, including the main body, rotors, and other relevant components.
Once the geometry was finalized, it was imported into ANSYS Meshing for discretization. The meshing process involved dividing the computational domain into smaller elements, creating a mesh that accurately represented the quadcopter’s geometry. Care was taken to ensure that the mesh quality was high, with appropriate refinement in regions of interest, such as near the rotors and the quadcopter body.
The acoustic simulation of the quadcopter using ANSYS Fluent demonstrated the effectiveness of CFD in studying the noise characteristics of complex systems. The 3D symmetric model and the high-quality mesh ensured accurate and efficient simulations. The results obtained from this study can be used to optimize the quadcopter design, minimize noise emissions, and enhance the overall acoustic performance of the system.

Methodology
we employ ANSYS Fluent software and leverage the applications of Computational Fluid Dynamics (CFD) to absorb the sound level around the domain and generate sound by the propeller. In this simulation, To capture the rotational motion of the quadcopter blades with an angular velocity of 1200 RPM, we employed two mesh motion zones. These zones allowed for accurate simulation of the blade dynamics and airflow characteristics around the quadcopter.
Results
Acoustic performance is essential in quadrotors, as it can impact the system’s safety and efficiency. Excessive noise can be a safety hazard, as it can interfere with communication between the pilot and ground crew and disturb wildlife in the surrounding area.
In addition, noise can indicate inefficiencies in the system, such as unbalanced rotors or aerodynamic issues. By optimizing the acoustic performance of quadrotors, designers can improve their safety, efficiency, and overall performance. This can lead to more reliable and effective use of quadrotors in various applications, from aerial photography to search and rescue operations.
Turbulence can have a significant effect on the sound generation of a propeller. As the airflow around the propeller becomes more turbulent, it can cause pressure and velocity fluctuations, leading to increased noise levels.
This can be especially pronounced in the near-field region of the propeller, where the turbulent flow can interact with the blades and ring structure. Designers of propellers must take turbulence into account when optimizing their acoustic performance.

The simulation comparison between the toroidal and standard propellers is remarkable. The reduction of sound levels in the toroidal propeller seems quite significant. Excellent project execution and great potential for practical applications in noise-sensitive areas. Could you possibly detail whether these results have been validated with experimental data?

Thank you for your compliments on our project work. The simulation studies provide valuable insights, and we agree that the acoustic reduction achieved with the toroidal propeller is promising. We ensure that our CFD simulations aim for high accuracy, but due to the nature of this exchange, we don’t have direct access to the specific experimental validation data. However, it is standard practice to validate simulation results with experimental data or analytical solutions when possible. This would be the next step to ensuring our findings are as reliable as possible and can confidently inform future designs and applications.

The simulation results mentioned a significant noise reduction using a toroidal propeller. Was this reduction achieved through design modification of the propeller or by inherent qualities of the toroidal shape?
MR CFD Support –
The noise reduction achieved with the toroidal propeller is primarily due to the inherent qualities of its shape. The ring-shaped structure of the toroidal propeller helps absorb and dissipate sound waves, which contributes significantly to lower noise levels. However, specific design modifications and optimizations during the CFD simulation process may have enhanced these inherent acoustic benefits.
