  • Comprehensive Study Of Unsteady Pressure Pulsations Induced By The Spiral Vortex Structure In A Conical Diffuser 

    Štefan, David; Rudolf, Pavel; Hudec, Martin; Habán, Vladimír (Faculty of Technologies and Systems, 2015-09-09)
    The decelerated swirling flow often breaks down into helical structure which is unstable and causes unsteady velocity and pressure fields. The numerical and experimental investigation of this flow pattern is carried out ...
  • Dynamics of pressure pulsations in thin annular gap 

    Kůrečka, Jan; Himr, Daniel; Habán, Vladimír (IOP Publishing, 2021-06-15)
    Fluid pulsations can significantly influence behavior of bearings or sealing parts of hydraulic machines and therefore their operation. In this contribution, an analytical approach to solve pressure pulsations dynamics is ...
  • Inner Damping of Water in Conduit of Hydraulic Power Plant 

    Himr, Daniel; Habán, Vladimír; Štefan, David (MDPI, 2021-06-25)
    The operation of any hydraulic power plant is accompanied by pressure pulsations that are caused by vortex rope under the runner, rotor–stator interaction and various transitions during changes in operating conditions or ...
