Savonius rotor prototype based on wind tunnel testing

TL;DR: In this article, the Savonius rotor prototype was designed and tested in El-Arish at the Faculty of Engineering, Sinai University, and the results showed that the rotor gave considerable efficiency and began to give power at a relative low wind speed.

Abstract: In this work, it is planned to design and test a prototype of Savonius rotor in free wind based on the results of the previous experimental study. The prototype is designed and tested in El-Arish at the Faculty of Engineering, Sinai University. Although El-Arish has lower average yearly wind speed compared to other locations with higher average wind speed, like Hurghada. The results show that Savonius rotor prototype in El-Arish gives considerable efficiency and begins to give power at a relative low wind speed. While the energy generated from the Savonius rotor prototype in El-Arish is small, the cost of energy generated is competitive with other energy sources. The cost of kW hr generated from Savonius rotor is expected to be very low specially in locations with high average wind speed. The majority of the Egyptian locations having an average wind speed between 3.5 and 4.5 m/s. The cost of kW.hr generated from Savonius rotor in these locations is expected to be between 0.42 and 0.28 LE. In locations where average wind speed is 6 m/s, the cost of kW hr is expected to be 0.1 LE. Therefore the use of Savonius rotor will be attractive in many locations in Egypt and it can be used to pump water for irrigation of lands. This will save a great part of conventional energy sources used for this purpose and consequently reduces the environmental pollution. بط ُّيبرٕج تب زنط عنُ منًلج بناضأ يُنصحنا ةهٓطٔ ًٍثنا ةصيخر بَٓأب شيًحج ٗحنا ةيطأزنا تبُيبرٕحنا ٍي ْٗ ّيئإٓنا صٕيَٕف ّافخُي ءإْ , زصي بُٓئ ّييبُنا لٔعنا ٗف بٓياعخحطا ٍكًض ٗحنا ّيئإٓنا تبُيبرٕحنا مافا ٍي بٓهلجض كنذ . زحن ٗننٔأ وذٕنًَ ربناحخخٔ يُنصجٔ ىيًصج ىج مًلنا اذْ ٗف تبنطبي نا تئبنحَ ٗنه اعنًحلي زنتنا ءإنٓنا ٗنف ةنيئإٓنا صٕيَٕفبنط ةنُيب ةنيهكب مةنيكيَبكيًنا ٖٕن نا ةنطعُْ ىنظ ب موعن حًنا نئإًنا بنكيَبكيي منًلي ٗنف صٕيَٕفبط ةُيبزج ٍي وذبًَ ٗه ثضزجأ ٗحنا ةيهًلًنا ةيفًُٕنا ةليبج مةطعُٓنا . شضزلنا ةُضعي ٗف ٗنٔلأا وذًُٕنا رباحخخٔ يُصج ىج ءبُيط ةليبج مةطعُٓنا ةيهكب . شضزنلنا ٌأ ٍني ىأزنبنب اذنْ مةنافخُي نبنضر تب زنط عنُ ةقبط عينٕج ٗف أعاضٔ مةنٕ لي ةءبفكب مًلض ٗنٔلأا وذًُٕنا ٌا عجٔ ع نٔ ةافخًُنا نبضزنا تب زط تاذ ةضزصًنا قطبًُنا ٍي زاحلج . ٕحًنا ةنقبطنا ٍني منقا زاحلج صٕيَٕفبط ةُيبزج ٍي ةعنٕحًنا ةقبطنا ةءبنف ٌلأ كننذٔ ةنينبلنا تب زنظنا تاذ ةني فلأا تبنُيبزحنا ٍني ةعنن ةنقبطهن ٖزنخلأا رلبنصًنا ضفبنُجٔ ةنافخُي زناحلج صٕيَٕفبنط ةنُيبزج ٍني ةنجحًُنا ةنقبطنا ةعحٔ ةفهكج ٍكنٔ ممقأ صٕيَٕفبط ةُيبزج ةُيبزحنا ِذْ ءبشَلإ ةافخًُنا ةفهكحنا باظب كنذٔ . نُي ىظلي ٗف ةططٕحًنا نبضزنا ة زط ٌخ ٍينب ن ج زنصي قطب 3.54.5 m/s ٔ م دق ل ةنفهكج ٌأ عنجٔ kW hr ةنُيبزج ٍني تحنًُنا ٍيب حط زصي قطبُي ىظلي ٗف صٕيَٕفبط 0.42-0.28 LE ٗننخ منصحن ةنفهكحنا من ج إنط بنًُيب ماعنج ةننٕ لي ةنفهكج ٗنْٔ LE 0.1 ةططٕحًنا نبضزنا ة زط بٓب ٗحنا قطبًُنا ٗف m/s 6 . يبزج واعخحطخ ٌإف كنذنٔ ةزنيث قطبنُي ٗنف ةنقبطنا عينٕحن صٕيَٕفبط ةُ ةزنيا ةنيًْأ ّنن ٌٕكينط زنصي ٗنف . ٗن ارلأا ٖزنن ةنيس ا ِبنيًنا رنان تبناًهطنا ةرالخ ٗنف ةنُيبزحنا ِذنْ واعخحنطخ ٍنكًًنا ٍنئ ا ٍني بناضأ منه ض إنطٔ متباًهطنا ِذْ ةرالخ ٗف وعخحظًنا ٖعيه حنا لٕقٕنا ٍي ةنٕ لي تبيً زفٕض إط اذْ مةي ارشنا تبنثبلاَلإ ٗئيانا خٕهحهن ةااظًنا ةضرازتنا .
