How to find the power/torque of the vertical axis wind
I know how to find torque via CFD post for wind turbine, select the blade and axis in function calculator. But I find a big difference between the experiment and CFD value at high wind speed.
Vertical Axis Wind Turbine an overview ScienceDirect
Vertical axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically. Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective. This is an advantage on sites where the wind direction is highly variable. VAWTs can utilise winds from varying directions.
Vertical Axis Wind Turbines: Minimising Generator Losses
Vertical Axis Wind Turbines (VAWTs) tend to produce mechanical torque which varies significantly with rotor azimuth angle. The cost of the electrical generator is related to the peak generator torque which in turn depends on the choice of torque/speed control strategy. This choice of control strategy also affects the copper and iron losses of the generator; these can

Savonius wind turbine Wikipedia
Savonius wind turbines are a type of vertical-axis wind turbine (VAWT), used for converting the force of the wind into torque on a rotating shaft. The turbine consists of a number of aerofoils, usually—but not always—vertically mounted on a rotating shaft or framework, either ground stationed or tethered in airborne systems.

Self aligning torque Wikipedia
Self aligning torque, also known as aligning torque, aligning moment, SAT, or Mz, is the torque that a tire creates as it rolls along, which tends to steer it, i.e. rotate it around its vertical axis. In the presence of a non-zero slip angle, this torque tends to steer the tire toward the direction in which it
How do you calculate torque of Vertical Axis Wind
11.01.2011· Since a vertical axis has a blade surface that follows a caternary curve,similar to a shallow parabola, you have to draw a chord from the outer diameter of the blade to the attachment at the main shaft. The torque will be measured the midpoint of that chord will it crosses the curved blade. It is an average torque value.

Vertical Axis Wind Turbines Advantages & Disadvantages
Vertical axis wind turbines are not a new invention but are making their way into the mainstream renewable energy trends. Not all of the blades produce torque at the same time, which limits the efficiency of vertical systems in producing energy. Other blades are simply pushed along. There is also more drag on the blades when they rotate. Although a turbine can work in gusty winds, that is

Vertical torque responses to vestibular stimulation in
15.08.2011· Presumably, vertical torque would be generated only to compensate for a sense of rotation around a vertical axis. This would obviously be caused by a sense of head roll, assuming the head is first tilted up or down. However, the acceleration vector might also result in a sense of body rotation, if the head is displaced from the axis of body rotation, by leaning forwards for example. Hence
