AbstractThe paper considers the development of a technique for calculating the propagation of liquid pressure waves in pipelines for a large-scale experimental thermohydraulic model of a VVER-440 double-circuit steam generating plant. It is shown that the pressure compensator amplifies the pressure pulsations, as a Helmholtz resonator. As the Helmholtz resonator under certain conditions is a damper for acoustic oscillations of a given frequency, it is proposed to use an acoustic frequency filter of the Helmholtz resonator as an effective means of preventing vibroacoustic resonances at the NPP.A technique for calculating the propagation of pressure waves in the pipelines of the experimental stand of the MPEI TPP is developed. It is shown that the volume compensator can amplify the acting oscillations.
