Description	Při modelování vysokofrekvenčních pulsací je rozhodující tlumící schopnost. Dosud se předpokládalo, že tlumení je dáno pouze první viskozitou nebo kvadrátem průtoku. V článku je popsán model tlumení zahrnující účinky druhé viskozity. Druhá viskozita byla experimentálně zjištěna v laboratořích odboru Fluidního inženýrství Victora Kaplana Vysokého učení technického v Brně. Matematický model systému s hydraulickým strojem (vodní turbínou), rovným potrubím a uzly reprezentoval rozváděcí kolo, spirální těleso a přivaděč. (cs) At the modeling of high-frequency pressure oscillations the damping function is decisive. Up to now it was assumed that the damping is given by the first or the second power of discharge. In this paper the damping model including the influence of fluid second viscosity is described. The second viscosity has been experimentally determined at the Hydraulic laboratory of the University of Technology in Brno, Czech Republic. The mathematical model of the system with hydraulic machine (water turbine) consists of straight pipes and nodes, where the straight pipes represent distributor channels, spiral case and penstock.
