Comprehension of UAV External Airflow Simulation
Project Description
Focussing on aerodynamic forces, stability, and design optimisation, this project uses ANSYS Fluent to simulate the airflow around a UAV (drone). Because of their remote control features, UAVs are commonly utilised in military and aviation sectors, therefore aerodynamic study is very vital.
Methodology
- Aerodynamic Design: CATIA was used to design the UAV's shape; SpaceClaim was used to hone it; ANSYS Meshing's unstructured mesh of 3,079,338 components was used to mesh it.
- Turbulence Modeling: High-speed airflow causes turbulence and flow separation that the conventional k-epsilon model with standard wall functions captures.
Conclusion
The simulation offers knowledge on pressure and velocity contours, streamlines, and velocity vectors surrounding the UAV. Among the main results are:
- Maximum Pressure and Velocity: Occur at the front and top of the UAV, respectively, with maximum velocity reaching roughly 43 m/s against an incoming airflow speed of 30 m/s—emphasizing acceleration due to the UAV’s structure.
- Flow Dynamics: The study shows vortex generation, flow separation, and other important aerodynamic phenomena, guiding design changes.
