Optimized component behavior, for instance of check valves, turned out to be crucial for good energetic performance of a hydraulic stepper converter. Despite their simple mechanical design, check valves have very complicated dynamical behavior due to different flow regimes which interact in a highly nonlinear way with the check valve’s plate motion. A model in the free CFD software OpenFOAM was able to simulate quite accurately this coupled fluid and solid body mechanics. The insight into the flow and motion details allowed an optimized design of the fast-check valves. View this paper
