Originální abstrakt

This paper is focused on the dynamical damper research of the high frequency pressure and flow pulsations in the vaneless space of the pump tubine. This pulsations rise as a result of the interaction between the impeller and distributor. From the theory is generally known, that the dynamical damper based on the Helmholtz resonator principle is placed into the antinodes of the pressure eigen wave shape, if the standing wave is assumed. The eigen and excitated wave shapes were determined by the transfer matrix method. The one-dimensional theory and the second viscosity were assumed.
