Документ Dynamics of oscillation processes in siphon U-tubes(Харківський національний університет імені В. Н. Каразіна, 2015) Tkachenko, O. Y.; Kazachkov, A. R.; Lykah, V. A.; Minakova, K. A.; Syrkin, E. S.The dynamics of oscillation processes in a siphon U-tube is studied for the system of connected vessels fi lled with homogeneous liquid. The equations and phase paths describing the motion of non-viscous liquid and fountain eff ects are given, oscillation frequencies are considered. Oscillations are nonlinear in general case, but they turn into linear by setting special parameters of the system. Phase portraits are obtained and their dependences on parameters of the system are analyzed for the linear and non-linear cases. It is shown that the behavior of the deep and shallow water in such a system could be discussed using analogy with the propagation of elastic waves in condensed matter. Some interesting analogies between a siphon U-tube and hydrodynamic, mechanical, electromagnetic phenomena, wave motion are also analyzed.Документ Liquid Nonlinear Oscillations in the U-Tube System(NTU "KhPI", 2016) Kazachkov, A. R.; Lykah, V. A.; Minakova, K. A.; Syrkin, E. S.; Tkachenko, O. Y.Dynamics of oscillation processes in a siphon U-tube is studied for the system of connected vessels filled with homogeneous liquid. The equations and phase paths describing the motion of viscous and non-viscous liquids are given, oscillation frequencies are considered. Oscillations are nonlinear in general case, but they turn into linear by setting specific parameter values of the system. Phase portraits are obtained and their dependences on parameters of the system are analyzedfor both linear and non-linear cases.
