Vertical Axis Wind Turbine Aerodynamics and Design
#engineering #educational #stem
In this video I show you how the aerodynamics of a (lift-type) vertical axis wind turbine work, and some of the design challenges and solutions of VAWT design.
01:47 Types of Darrieus/ lift-type vertical axis wind turbines
02:25 How to analyse helical and egg-beater shape VAWTs
03:14 Aerodynamic operating principle of a vertical axis wind turbine (simplified)
04:37 How the VAWT velocity triangle changes as the blade rotates
04:50 equations to find relative wind speed and angle of attack
04:53 Tangential force equation
05:58 Effect of tip speed ratio on VAWT blade stall
06:25 VAWT design challenges
06:34 Fatigue loading
06:59 Torque ripple
07:53 Design changes to overcome fatigue loading and torque ripple challenges
08:56 Effect of adding more blades
09:11 Helical blade design
09:34 VAWT blade pitch control
10:14 My opinion: Efficiency vs Complexity is a tradeoff
10:54 Niches where vertical axis turbines are better suited than horizontal axis turbines
For an overview of vertical axis wind turbines and the advantages and disadvantages compared to horizontal axis wind turbines see this video:
