Question: What are the similarities and differences between horizontal axis wind turbine (HAWT) and vertical axis wind turbine (VAWT)?
Solution:
1. Differences
- Rotating axis of VAWT is perpendicular to direction of wind. While in case of HAWT it is parallel to direction of wind.
- Efficiency in VAWT is low. While in case of HAWT is high.
- Maintenance cost in case of VAWT is low. While in HAWT it is high.
2. Similarities
- Both are work producing devices.
- Both are good options for electricity generation.
- Both involve fatigue and bending moments.
