2013-11-20 total mechanical power is reduced into a new, simple relation: P =F x⋅vx +F y ⋅vy +M z ⋅ωz (5) This is the formula to obtain the power consumption in the center of the dynamometer with the forces and moments provided by dynamometer. But to be closer to reality, one has to obtain this power at the tip of the tooth. For this it is

2014-8-2 Using a calculation code based on the Multiple Stream Tube Model, it was highlighted that the power coefficient is influenced by both rotor solidity and Reynolds number. By analysing the factors which influence the Reynolds number, it was found that the ratio between blade height and rotor radius (aspect ratio) influences the Reynolds number and as a consequence the power coe

2014-8-2 Figure 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 one (thicker blades ...
