Effect of the number of blades and solidity on the performance of a vertical axis wind turbine [PDF]
, 2016 Two, three and four bladed phgr-shape Vertical Axis Wind Turbines are simulated using a free-wake vortex model. Two versions of the three and four bladed turbines are considered, one having the same chord length as the two-bladed turbine and the other ...

Optimal Design for Thrust Ripple Reduction of Stationary Distributed-Armature System [PDF]
Journal of Magnetics, 2016 Although the initial cost of permanent-magnet linear synchronous motors is high owing to the installation of armatures over the full length of the transportation lines, linear motors are useful for transportation systems because of their high speed, acceleration, and deceleration.
