Development of a Savonius vertical axis wind turbine operated water pump

Abstract: Wind energy is abundant, inexhaustible, affordable, environmentally preferable, and equally sustainable More researches are emerging in the analysis of wind energy in Nigeria and each have proven that great potential exist for wind power generation in Nigeria but sufficient results is yet to be achieved in terms of application The present research is intended to apply the technology of wind energy for pumping of water in rural Nigeria To achieve this, a savonius vertical axis wind turbine is developed To ensure, an optimum functioning system was developed and design consideration and conceptual design were drawn The best conceptual design was selected for development using decision matrix The system was evaluated for performance and UT363 Anemometer was used to measure the wind speed Results obtained indicate a swept area of 341 m2, power of wind of 3146 watts, blade tip speed and rotational speed wind of 738 rpm and 505 rpm were required for effective wind turbine operation Besides, an average wind speed of 349 m/sec was required to pump an average 4777 litres of water at an average time of 308 minutes

“Practical Analysis of A Small Wind Turbine for Domestic Use on Latitude 7.0670N, Longitude 6.2670E”

Abstract: This work focuses on the design and construction of a small wind turbine suitable for generating electricity in low wind speed regimeon Lat7.0670N, Long 6.2670Eat very low cost. The wind turbine was designed to generate 250 Watts of power at the rated speed of 6.5m/s. In the design process,the various components of the wind turbine were considered and all the loads liable to occur during all temporary and operating conditions were calculated theoretically and the designs were optimized to ensure that the turbine operates at full capacity.The turbine’s performance was such that generation hovered between 60 and 100 in the months of October and November while it skyrocket towards 200 watts in the month of December.From performance point of view the turbine has proved to be relatively efficient for power generation in Auchi, Edo state where this work was carried out.

Evaluation of domestic energy preference in Nigeria cities: a case study of Warri, Benin, Port Harcourt, and Calabar

Abstract: The significance of energy in human lives cannot be overemphasized. It is crucial to all facets of economic growth, progress, and development as well as poverty eradication and security. Household energy is generally required for a variety of purposes. It is required for lighting and heating. This study evaluated domestic energy utilization in major Nigeria cities using Warri, Benin, Port Harcourt, and Calabar as a case study. A total of four locations with the highest population were targeted at each selected city. Responses were randomly selected from energy utilization in the selected region. A total of 1439 questionnaires were administered all through the selected cities in this study. Data obtained were evaluated using descriptive statistic. The result obtained revealed that kerosene has the highest percentage of utilization (88%), LNG (68.9%), electricity (67.7%), PMS (67.1), diesel (5.6%), charcoal (16.4%), wood (28.2%), and solar (3%) within these cities. Therefore, kerosene is the most preferred energy and this can be as a result of cost when compared to LNG, electricity, PMS, diesel, charcoal, solar, and wood fuel.

Wind Characteristics and Wind Energy Potential in Andean Towns in Northern Peru between 2016 and 2020: A Case Study of the City of Chachapoyas

Abstract: Currently, climate change and population growth have a significant impact on human beings. Furthermore, these factors are generating a great need for energy to sustain present-day pace of life. For this reason, this research aims to determine the wind potential of the city of Chachapoyas, through the study of wind direction and speed using a wind rose. Data were obtained from the Metrological Station located on the University Campus of the National University Toribio Rodríguez de Mendoza (UNTRM) for developing this diagram. The mentioned station had 15% of missing data, therefore a quality control of the data and multiple imputations was carried out to fill in any missing data. The results obtained show that the winds in this area are mostly weak (from 0 to 3 m/s) with an East-Northeast (ENE) and Northeast (NE) direction for both the studied period and for each year of the period. It has also been determined that there is a difference between the wet and dry seasons in terms of wind frequency. Finally, we conclude that, in the city of Chachapoyas, it is possible to generate wind energy by using low-power vertical axis wind turbines.
