Wind turbine utilization for water pumping in Jordan
Journal of wind engineering and industrial …, 2003
This paper presents a survey of wind turbine water-pumping applications in Jordan, either by direct pumping through mechanical means, or indirectly by generating electric power to drive pumps. Up until now Jordan does not have any proven indigenous traditional energy resources such as coal, gas, or oil. Therefore, we have to look at renewable energy resources with all sincerity and concern to utilize it for multi-purpose functions such as water pumping. We recommend using wind energy to meet the energy requirements for remote villages, settlements, and farms of Jordan. r

Most of the rural areas do not have access to potable water. In some regions of the country access potable water is available through use of manual pumping and Diesel engine. The aim of the project is to provide water pumping facility which can be used instead of electrical pump in order to lift water to tanks for irrigation. It is achieved by using windmill water pump which use renewable wind energy, and preserve the environment. An economic comparison is conducted, on the basis of cost analysis, for wind mill and Diesel water pumping systems and the results shows that windmill water pumping systems are more feasible than diesel based systems.
DESIGN AND FABRICATION OF WATER PUMPING WINDMILL
iii Abstract The design and model of hybrid power system, consisted of renewable energy source (wind energy). It converts wind power into mechanical energy. Burden on national grid over comes,electricity bill reduces and we get energy in environmental friendly manner. This work explains the mechanism to utilize the renewable energy as first option,whether other conventional source are available or not. For irrigation, farm, home and community water supply. Excellent for filling lakes, reservoirs and tanks. All mechanical design is simple and efficient.It is perfect solution for providing a lifetime of free water.Wind energy systems used world wide since 1970. Pakistan have a huge renewable energy potential to meet their energy needs. This type of turbine is unusual and its application for obtaining useful energy from air stream is an alternative to the use of conventional wind turbines.
The main source of energy has been coal, oil, natural gas, nuclear energy, wood and coal. However, all these sources are limited and are the main cause of pollution and this has led to development and more focus on sustainable energy supply with minimum pollution effects. Hence research and analysis has shown that wind energy, solar energy and biomass are the most prominent solutions to the above problems because they are eco-friendly and readily available in nature.
Performance of Wind Pump Prototype
A wind pump prototype with 3.6 m rotor diameter, 19 m hub height above ground and 0.22 mm reciprocating pump stroke has been developed at the Department of Mechanical Engineering, Mekelle University. The prototype was designed and manufactured locally. Theoretical model based on combined efficiency of the rotor and the reciprocating pump was used to estimate the performance of the wind pump. One year wind speed data collected at 10 m height was extrapolated to the wind pump hub height using wind shear coefficient. The model assumed balanced rotor power and reciprocating pump, hence did not consider the effect of pump size. The theoretical model estimated the average daily discharge to be around 50 m 3 and 30 m 3 at 8 m and 12 m head, respectively. The prototype was tested with the same pump stroke but two different size pumps at two different heads. The pumps were with internal diameter of 55 and 70 mm and the test heads were at 8 and 12 m. Measurement of the flow rate, rotational speed and wind speed were made every 10 minutes during the test period. The data collected were analyzed to find the performance of the wind pump at the two test heads and two pump sizes. The flow rate data was plotted against binned wind speed data to determine the linear fit function. The linear fit function was then used to estimate the flow rate at any wind speed. With the 55 mm pump the measured average daily discharge was 20 and 19 m 3 at 8 m and 12 m head, respectively. With the 70 mm pump the measured average daily discharge was 41 m 3 and 30 m 3 at 8 m and 12 m head, respectively.

Design and Development of Windmill Operated Water Pump
The imminent exhaustion of fossil energy sources,spreading global warming,expanding greenhouse effect , higher need of energy , less availability of power supplies motivates us to use renewable source of energy like wind-energy which is most prominent for our suitable application.Small wind turbines need to be cost effective, loyal, affordable minimum maintenance cost for any average person. It produces costlier electricity than medium and large scaled wind mills, specially in areas where availability of wind sites are less and in self-governing applications. However, after perfectly sized and used at optimal working climate, small-scale wind mills could be a dependable energy source and produce socioeconomically valuable energy not only in developing countries but also in local applications. The small-scaled wind mills have different aerodynamic behaviour than their large-scale wind mills. Poor performance of small wind mills is due to laminar separation and in turns on the rotor blades because of low Reynolds number (Re) resulting from low wind speeds and small rotor capacity. Low Reynolds number airfoils permits starting at lower wind velocity , increasing the starting torque and thus improving the overall performance of the turbine .Designing of rotor of windmill will includes optimizing the rotor and its components to achieve maximum power coefficient and efficiency. The pitch twist and allotment of chord length are optimized based on conservation of angular momentum and theory of aerodynamic forces on an airfoil. Blade Element Momentum (BEM) theory is first derived then used to conduct a parametric study that will determine if the optimized values of blade pitch and chord length create the most efficient blade geometry.
Design and Development of Wind Power Water Lifting Pump Mechanism
As an energy source, wind is free and does not need to be imported from other countries. Currently the popularity of wind power is still increasing worldwide. Denmark is one of many countries who are continually planning ahead in the development of wind power. Today, 25% of their electrical power is generated from wind with a goal of 50% for the year 2020. A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails. Originally, windmills were developed for milling grain for food production. In the course of history, the windmill machinery was adapted to many other industrial uses. An important non-milling use is to pump water, either for land drainage or to extract groundwater. A wind pump is a windmill used for pumping water, either as a source of fresh water from wells, or for draining low-lying areas of land. Wind pumps are used when electricity is not available. In this paper, it is described the detail design and development, experimentation of wind power water pump mechanism which is today's need for rural development .In further paper, the objective is to implement the design concept for the rural development.

The wind, among renewable energies, can play a important role for the water supply, irrigation of agricultural land and the generation of electrical energy. In fact, groundwater can be pumped using wind energy. This paper presents the perspectives of wind mechanical pumping in eight synoptic sites distributed at the Tunisian south. Map of Water Resources showed that Tunisia south is characterized by its aridity and the vulnerability of its land to desertification. Also, the study is interested at the energy evaluation of the wind turbine SEN 5000 P8. Based on its curve characteristic of power, we studied his energy profitability in the various sites.
Renewable and Sustainable Energy Reviews, 2012
An attempt has been made, may be first time in Saudi Arabia, to utilize power of the wind for pumping the water for remotely located inhabitants not connected with national power grid. Small turbines of 1-10 kW have been chosen in conjunction with Goulds 45 J model water pumps to produce energy from wind and pump water using the produced energy at Arar, Rawdat Ben Habbas and Juaymah localities in Saudi Arabia. Wind speed measurements made at different heights using 40 m tall towers have been utilized in the present work. Higher wind speeds were noticed during summer time compared to winter time at all the locations. Both energy yield and cost of energy point of view, 2.5 kW wind turbine from Proven was found to be most suitable for wind power generation at all sites. It is shown that annual total water pumping capacity of 30,000 m 3 is possible from a depth of total dynamic head of 50 m when using 2.5 kW Proven wind turbine with hub heights 15-40 m at all three sites with cost of water pumping as low as 1.28 USb/m 3 .
