Abstract
The utilization of renewable energy resources such as wind energy has increased recently due to the rising concern regarding global warming and the associated impact upon climate change, the increasingly rapid depletion of fossil fuel resources and the desire to maximize security of fuel supply. This study deals with autonomous wind pump applications for remote areas in Jordan. The performance of roto-dynamic wind-driven pumps under normal operating conditions has been estimated based on the mathematical model proposed by Mathew and Pandey for the integrated output of wind-driven roto-dynamic pumps. The effects of the specific speed and specific diameter ratios and the gear ratio on the size of the pump selected have been investigated. Specifications and the performance of piston pumps have also been investigated under the same conditions for comparison purposes. It is clear that the roto-dynamic wind-driven pumps offer better performance than the piston pumps.
