Davydenko A. Solution of direct three-dimensional hydrodynamic task for vans systems of axial type hydraulic machines by peculiarities method

Flow of a liquid in a flowing part of the hydraulic machine. The development of the solution of a three-dimensional straight line of a task with the purpose of definition characteristics of the moments on bladed systems. Methods of research and equipment: mathematical modeling, COMPUTER. Is designed and the model and technique of calculation of three-dimensional inviscid flow of a liquid in a flowing part (FP) of the bladed hydraulic machine of an axial type is realised, which one allows to allow for interaction interference of members a FP, the designed model is applied to the analysis and calculation of the hydrodynamic moments on blades of impellors (I) of hydromachines; for the first time for a spatial case the numerical researches of the hydrodynamic moments on a blades I are executed in view of members a FP, the designed software allows with the help of numerical experiment to conduct researches by an estimation characteristics o f the moments on blades I of the hydromachines and to replace physical experiment numerical. Is introduced in JSC "Тurboatom" (Kharkov) and in JSC "SMPO by him M.V.Frunze " (Sumy). Hydromachine-building industry.
