Original abstract

The methodology of determining the additional effects of a liquid acting on hydrodynamic machine rotor is presented in the paper. Special attention is paid to the force effects of the liquid inside the hydrodynamic sealing gap. A new mathematical model is derived from which is evident an influence of different parameters of the liquid bond on the additional stiffness, mass and damping.

Czech abstract

V práci je uvedena metodika určení přídavných účinků kapaliny, působící na rotor hydrodynamického stroje. Speciální pozornost je věnována silovým účinkům kapaliny v hydrodynamické těsnící spáře. Je odvozen nový matematický model, ze kterého je zřejmý vliv jednotlivých parametrů kapalinové vrstvy na přídavnou tuhost, hmotnost a tlumení.
