  • Experimental investigations of pipeline filling and emptying in a small-scale apparatus = Eksperimentalne raziskave polnjenja in praznjenja cevovoda malih izmer
    Karadžić, Uroš ; Bergant, Anton
    This paper serves as a reference for further investigations of pipeline filling and emptying in a relatively small-scale pipeline apparatus. The apparatus consists of an upstream end high-pressurized ... tank, horizontal steel pipeline, four valve units positioned along the pipeline including the endpoints, and a downstream end tank. The filling of an initially empty pipeline is performed by a sudden opening of the valve positioned at the high-pressurized tank filled with water. The pipelineemptying process is accomplished by high-pressurized air supplied from the air reservoir installed at the high-pressurized tank. The high-pressurized tank is closed, and the downstream end valve is opened. Experimental results indicate that pressure fluctuations are larger for pipeline filling in comparison to pipeline emptying. It is shown that a piezoelectric transducer with a fixed relatively low discharge time constant is not entirely appropriate for accurate low-frequency pressure measurements.
