Katup merupakan peralatan mekanik statis yang bertujuan untuk mengontrol aliran dan tekanan dalam suatu sistem perpipaan. Pemilihan jenis katup, bentuk desain material memiliki peran sangat penting kinerja kehandalan sistem. Pompa hidram bekerja dengan memanfaatkan proses palu air. Terjadinya air akan mengakibatkan sebagian menuju ke tabung udara lagi mengalami balik pada pipa penggerak. Penceg...

Smart isolation devices (SIDs) are commonly used in pressurized subsea pipelines that need to be maintained or repaired. The sudden stoppage of the SID may cause large water hammer pressures, which threaten both pipeline and SID. This paper proposes a simulation method by using coupled dynamic mesh technique simulate pressures pipeline. Unlike other simulations, this is first with moving object...

A pipe water hammer with column separation was studied in a range of flow rates (Re=465 to 2239) test rig an acrylic glass observation section. Pressure transients were measured piezoresistive pressure sensors, while the gas evaporation and condensation captured by high-speed recording Photron SA-Z at frame rate 75,000 fps. Separation lengths estimated threshold value images. The results did no...

A surge tank, as one of the most common control facilities, is applied to head pressure levels in long pressurized pipelines during water hammer occurrence. The cost-effective operation tanks highly affected by their characteristics (i.e., tank diameter and inlet tanks) can effectively reduce repercussion hammers. This investigation utilized method (MOC) order simulate behavior transient flow a...
