Objectives
To study the aerodynamic and acoustic parameters affecting fan performance and noise.
To design fan blades inspired by owl wing morphology.
To perform CFD analysis to compare airflow, noise levels, velocity, and pressure.
To evaluate which owl-inspired design iteration can reduce noise while maintaining or improving airflow and pressure.
To gain insights into applying nature-inspired design principles for quieter and more efficient fan blades.
Applications
Applications
1. Ceiling Fans (Residential Use)
Used in homes, offices, and hotels for quiet and efficient air circulation.
Example: Owl-inspired blade edges reduce turbulence and noise levels.
2. Industrial Ventilation Systems
Nature-inspired blades improve airflow efficiency in factories and warehouses.
Reduce energy consumption while maintaining strong air delivery.
3. Cooling Fans for Electronics and HVAC Systems
Used in air conditioners, refrigerators, and computers to enhance cooling with less power.
Humpback whale fin-inspired designs increase lift and minimize drag.
4. Automotive and Aerospace Fans
Applied in radiator cooling fans, drones, and aircraft turbines.
Bird wing or insect wing-inspired geometries help optimize thrust and minimize noise.
5. Wind Turbines and Energy Systems
Bio-inspired blade designs (e.g., humpback whale tubercles) improve energy capture efficiency.
Allow turbines to work effectively at low wind speeds.
6. Exhaust and Air Purification Systems
Used in air purifiers, exhaust fans, and ventilation ducts to enhance airflow direction and reduce vibration.
7. Marine and Underwater Propulsion
Inspired by fish fins or dolphin tails, providing efficient propulsion with reduced cavitation and noise.
