Keep ReadingA vertical wind turbine has changed the notion of imagining windmills with blades rotating at horizontal axis. One can easily compare the rotation of a vertical axis wind turbine with a coin spinning along vertical axis. So, a modified configuration of blades and some good results can be obtained through vertical wind turbines.
Keep ReadingIn short, what truly classifies horizontal and vertical turbines is their orientation relative to the wind. Horizontal turbines spin on an axis that is parallel to the direction of the wind, while vertical turbines are oriented perpendicular to the direction of the wind. Horizontal wind turbines have become the norm over the past few decades.
Keep ReadingThe intent of this project, created in collaboration with Mech425, is to identify the best angle for flat, uniform blades in relationship to the air stream. The angle of the blades should be optimized to convert the most amount of energy into rotational motion. Flat blades are used in conjunction with vertical axis turbines and the design is ...

Keep ReadingVertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.

Keep ReadingAbstract. Vertical Axis Wind Turbines (VAWTs) represent a unique form of power-generating technology. Historically, they have been relegated to fulfilling a small niche market in commercially available wind turbines due to their "yaw-less" design. Current VAWT designs lag behind their Horizontal Axis Wind Turbine (HAWT) counterparts in ...
Keep ReadingA Vertical Windmill. Oct 16, 2009. Vertical-axel windmills need fewer moving parts than traditional designs, keeping maintenance costs lower. Turbines with blades that revolve on a vertical rather than horizontal axis can improve the efficiency of clean wind generators, according to the Swedish manufacturer Vertical Wind.

Keep ReadingThe wind usually flows across the planet rather than in updraft or downdraft conditions. For the same reason, propeller driven aircraft tend to move in the direction of thrust of the propeller blades. Conventional ones generally move forward and vertical take-off and helicopters can move vertically.
Keep ReadingFigure 5 shows two vertical-axis turbines with identical design power, blade number and aerodynamic profile (NACA 0018) but with two different aspect ratios (AR 1 = 2; AR 2 = 0.4). As stated above, the turbine with the lowest AR will have the highest power coefficient and the lowest rotational velocity. This turbine will display two further advantages: firstly, a structural …
