Näkemys oikeudenmukaisuudesta ja kihlakunnantuomarin viraltapano 1700-luvun puolivälin Vanhassa Suomessa
2021
Sven Johan Östring hoiti Vanhassa Suomessa sijainneen Savonlinnan tuomiokunnan kihlakunnantuomarin virkaa reilun vuosikymmen ajan keväästä 1747 kesään 1760. Kihlakunnantuomarin ja tuomiokunnan rahvaan välit kärjistyivät 1750-luvun lopulla talonpoikien valittaessa toistuvasti tuomari Östringin väärinkäytöksistä. Talonpoikien mukaan kihlakunnantuomari Östring oli heidän vihamiehensä. Artikkelissa kysytään, miten virkavirhevalitusprosessit etenivät ja mitkä syyt johtivat lopulta kihlakunnantuomarin viraltapanoon. Kihlakunnantuomari Östringin väärinkäytökset olivat luonteeltaan pääasiassa taloudellisia. Valituksissa korostui kuitenkin taloudellisia menetyksiä vahvemmin talonpoikien näkemys oike…
Slotted Blades Savonius Wind Turbine Analysis by CFD
2013
In this paper a new bucket configuration for a Savonius wind generator is proposed. Numerical analyses are performed to estimate the performances of the proposed configuration by means of the commercial code COMSOL Multiphysics® with respect to Savonius wind turbine with overlap only. Parametric analyses are performed, for a fixed overlap ratio, by varying the slot position; the results show that for slot positioned near the blade root, the Savonius rotor improves performances at low tip speed ratio, evidencing a better starting torque. This circumstance is confirmed by static analyses performed on the slotted blades in order to investigate the starting characteristic of the proposed Savoni…
Computer Aided Optimization Via Simulation Tools of Energy Generation Systems With Universal Small Wind Turbines
2012
This paper considers the general issues in the project and the optimization of energy generation systems using small universal wind turbines, suitable in Distributed Generation (DG) and computer aided optimization for a better exploitation of wind source. Optimization in this field reveal to be more and more important because the local generation and consumption of electrical power, even for grid connected generators can suffers for unevenness of wind source exploitation, also in terms of wrong directions and in not regular wind flows. Computer aided design and optimization of small plants may give significant improvements in the development of the wind source also in accordance with the pr…

Performance study of a Helical Savonius hydrokinetic turbine with a new deflector system design
2019
Abstract The use of renewable energy sources has becoming a necessity to generate electricity. Helical Savonius rotors have been preferred for small-scale hydropower generation. Numerous studies were carried out to improve the performance of the Helical Savonius rotor which has not been fully explored. In this paper, an experimental study was carried out to evaluate the performance of a Helical Savonius water rotor in an irrigation channel. In order to enhance the performance of the studied water rotor, a new deflector system design was proposed. Different configurations of the proposed deflector system were tested numerically using the commercial software ANSYS FLUENT 17.0. Without a defle…
On the Effect of Slotted Blades on Savonius Wind Generator Performances by CFD Analysis
2012
In this paper a new bucket configuration for Savonius wind generator is proposed. With the aim to increase the effect of the overlap ratio RS on the wind turbine performances and to increase the amount of lift force able to produce torque and power, slotted blades are investigated by means of the Computational Fluid Dynamics analysis. The numerical analyses are performed by Comsol Multiphysics® and the results obtained for a Savonius wind turbine with overlap only are compared to numerical and experimental benchmarks. Parametric analyses are performed, for fixed overlap ratio, by varying the slot angle β and the results show that for low angle β the Savonius rotor exploits improved performa…
Viipurilainen musiikkielämä Savonlinnassa
2021
This text examines musical relations between Savonlinna and Vyborg, as well as the hobby of music amongst the Karelian migrants in Savonlinna. The hobby of music united evacuees from Vyborg after the wars. This was influenced by pre-war contacts that facilitated their adaptation to Savonlinna. The Roma population with a Karelian background was also part of this musical tradition, but there is still little research on this topic. peerReviewed
Performance improvement of a Savonius water rotor with novel blade shapes
2021
Abstract Savonius water rotor is a prominent drag based turbine able to extract energy available in flowing water with low velocity like river streams, tidal currents or other man made water canals. However, in view of its low performance, an enhanced design of the rotor blades is necessary to better its efficiency. Therefore, the present study aims to improve the efficiency of Savonius rotor by changing the blade design. Different blade shapes were investigated numerically using computational fluid dynamics (CFD). Using conventional design, the peak power coefficient was found to be 0.166 at tip-speed ratio of 0.78. However, the peak power coefficient reaches 0.184 using the optimal blade …
