    • A concept of risk prioritization in FMEA analysis for fluid power systems 

      Fabiś-Domagała, Joanna; Domagala, Mariusz; Momeni, Hassan (Peer reviewed; Journal article, 2021)
      FMEA analysis is a tool of quality improvement that has been widely used for decades. Its classical version prioritizes risk of failure by risk priority number (RPN). The RPN is a product of severity (S), occurrence (O), ...

    • Fluid-Structure Interaction Simulation of Flow Control Valve 

      Domagala, Mariusz; Momeni, Hassan; Domagala-Fabis, Joanna; Bikass, Saeed; Filo, Grzegorz; Amzin, Shokri (Journal article, 2020)
      Flow control valves are commonly used in fluid power systems. Controlled by proportional solenoid allows to control flow rate irrespective of pressure on inlet or outlet of the valve. Simulation of such valve is complex ...

    • The Influence of Oil Contamination on Flow Control Valve Operation 

      Domagala, Mariusz; Momeni, Hassan; Fabis-Domagala, Joanna (Peer reviewed; Journal article, 2022)
      This study presents CFD simulations of the flow of contaminated oil inside a control valve to investigate the influence of solid contaminants on the valve operational features. The Euler-Lagrange approach has been used to ...
