Tynyanova I. Improvement of flow space Francis turbines on the basis of design of hydrodynamic characteristics of the blade systems

Object of research is a working process of Francis turbines in the range of the basic operating modes. The purpose of research is perfection of flow space of Francis turbines on the basis of mathematical design of its hydrodynamic characteristics. Methods of researches are based on the fundamental laws of mechanics of liquid and gas, methods of mathematical and physical design of working process of hydroturbines. For the construction of mathematical model of working process, analysis of forming of hydrodynamic characteristics. Theoretical and practical results are the use of the developed models, algorithms and their programmatic realization, results of calculations for prognostication of power indexes, multiple analysis of influence of geometrical parameters on the separate types of hydraulic losses, leadthroughs of optimization calculations at planning of flow spaces of hydroturbines. The complex of the application programs is created for planning and calculation of runners, and program of calculation of perfection universal description of flow space of hydroturbine. The developed programs can be used both for planning of hydroturbine equipment for again built hydroelectric power plant and during modernization of existing. Their application allows to reduce the planning terms, decrease the volume of research and project works, improve quality of developments of flow space. Dissertation job performances were used in research work between NTU "KHPI" and factory of heavy engineering of BHEL, Bhopal, India at planning HPP.
