Methodology

This project combines the biomimetic design based on the morphology of the owl wings with the adapted computational fluid dynamics (CFD) and acoustic analysis to design and test the fan blades that offer the best noise reduction and airflow efficiency. Figure 3: Represents the flow that was followed for this project. To start the project, a comprehensive literature review was conducted in order to get to know about different types of fans, geometries of blades and also which are the main factors that affect the aerodynamic noise and airflow performance. Bio-inspired principles, in particular, the silent flight properties of owls, were taken into consideration specifically to inform the design changes. 

• Began the project with an extensive literature review on different types of fans, blade geometries, and factors influencing noise and airflow.​

• Selected a commercial fan and performed reverse engineering to extract key design dimensions.​

• Created the base CAD model in CATIA using the obtained measurements.​

• Conducted optimization of the blade design inspired by owl wing morphology to achieve noise reduction and improved airflow efficiency.​

• Analysis of the optimized model.
