Abstract
Vertical tubular turbine essentially belongs to the Kaplan type of turbines, however, without a spiral case. The main objective of the research is to develop a new low specific speed turbine with high efficiency. Flow analysis will be performed by standard numerical methods (Finite Volume Method). Computational analysis of hydraulic characteristics of the turbine includes an inlet elbow, distributor, turbine runner and draft tube. First, the theoretical model will be verified by the laboratory and on-site tests available for medium specific speed turbines. A verified model will be then used for development of the new low specific speed turbine. A novel approach combinig computational fluid dynamics and stress analysis will be used in order to obtain minimum weight and dimensions of turbine components.
Significance for science
Relevance of project results for science development may be summarized as follows: - better understanding of flow physics in the vertical tubular turbine flow-passage system with particular emphasis on flow-interactions between turbine components. Better understanding of flow physics in the vertical tubular turbine components enables optimal design of the turbine with high efficiency. - a novel approach combinig computational fluid dynamics and stress analysis in order to obtain minimum weight and dimensions of turbine components.
Significance for the country
Relevance of the research results to the development of Slovenia may be summarized as follows: - industrial growth in field of manufacturing of power generation equipment - new jobs as a consequence of industrial growth - improved knowledge in the field of hydropower design and construction in industry and civil sector (University) - application of renewable energy sources - continuation od 160 years long tradition of manufacturing of water turbines in Slovenia - promotion of Slovenian products in the country and abroad
