20.500.12556/RUL-128413 Determining optimum rotary blade design for wind-powered water-pumping systems for local selected sites Določitev optimalne oblike lopatic za sistem črpanja vode na vetrno energijo na izbranih lokacijah The design of a windmill rotor is critical for harnessing wind energy. In this work, a study is conducted to optimize the design and performance of a rotor blade that is suitable for low wind conditions. The windmills' rotor blades are aerodynamically designed based on the SG6043 airfoil and wind speed data at local selected sites. The aerodynamic profile of the rotor blade that can provide a maximum power coefficient, which is the relation between real rotor performance and the available wind energy on a given reference area, was calculated. Different parameters, such as blade shapes, chord distributions, tip speed ratio, geometries set angles, etc., were used to optimize the blade design with the objective of extracting maximum wind power for a water pumping system. Windmill rotor of 10.74 m, 7.34 m, and 6.34 m diameter with three blades were obtained for the selected sites at Abomsa, Metehara, and Ziway in south-east Ethiopia. During the rotary blades performance optimization, blade element momentum (BEM) theory and solving iteration by MATLAB* coding were used. boundary element method rotary sizing wind power hydraulic power power coefficient water pumping systems metoda robnih elementov dimenzioniranje vetrnic vetrna energija hidravlična moč koeficient moči sistemi za črpanje vode true false true Angleški jezik Slovenski jezik Članek v reviji 2021-07-12 09:17:54 2021-07-12 09:18:02 2025-03-11 14:24:02 0000-00-00 00:00:00 2021 0 0 Str. 214-222 no. 5 Vol. 67 May 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.548 0039-2480 10.5545/sv-jme.2021.7104 69912579 RAZ_Mohammed_Abdulbasit_2021.pdf RAZ_Mohammed_Abdulbasit_2021.pdf 1 5A531DA024130DFF3CA25BBCD6333C8C 7eaadd1bd248cc581cc048d70ddb959593bb8db7a1985486beb3092546988186 5c084252-e2e4-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145140 https://www.sv-jme.eu/sl/article/determining-optimum-rotary-blade-design-for-wind-power-water-pumping-system-for-local-selected-sites/ 1 28970bc9-e2e1-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145139 Fakulteta za strojništvo Strojniški vestnik 0 0 0
