Розрахунково-експериментальне визначення параметрів, що характеризують динаміку кавітуючих шнековідцентрових насосів різних конструкцій, типорозміру і продуктивності Head Pilipenko Viktor Vassilyevich, Registration Date 24-02-2003 Organization Institute of Technical Mechanics NASU and NSAU popup.description2 Research object: compressor stage of modern aircraft gas-turbine (GTE) and cavitating inducer-centrifugal pumps of liquid-propellant rocket engines (LPREs) with various dimensions and capacities. Research purpose: development of approaches to a numerical simulation of nonsteady three-dimensional gas flows through vane canals GTEs of compressor stages as well as verification of a mathematical model for the dynamics of LPREs cavitating inducer-centrifugal pumps by using current and new results of dynamical tests of inducer-centrifugal pumps. Research method: numerical simulation of three-dimensional turbulent gas flows on the basis of the averaged Navier-Stokes equation and information- analytical approach to experimentally calculated dependencies. Analytical and practical results: a procedure for a numerical solution of nonsteady averaged Navier-Stokes equations of the compressible gas, the energy equation and equations for the turbulence model is given. Results to systematize a lot of experimental dataare presented and parametric dependencies characterized a cavitation flow through inducer-centrifugal pump on pump operating parameters are given. Applications: aircraft and spacecraft companies. Product Description popup.authors popup.nrat_date 2020-04-02 Close
