A performance of roto-dynamic wind driven pump under normal operating conditions were estimated based on the mathematical model proposed by Mathew and Pandey for the integrated out put of wind-driven roto-dynamic pumps. Specifications of roto-dynamic and piston pumps are considered for the performance simulation under Jordanian climate conditions. The model which is applied to the roto-dynamic pumps...
The reliability problems associated with transmission or gearbox equipped wind turbines and the existing solutions of using direct drive gearless turbines and torque-splitting, are reviewed. As alternative solutions we propose the Geared Turbofan Engine (GTF) technology, and magnetically-levitated bearings from the aerospace industry, and the consideration of Continuously Variable Transmissions (CVTs)...
