In essence, it is an acoustic tube interferometer using the controlled closure of two valves. The device generates two water hammer waves that interfere with each other along the liquid-filled pipeline. The superposition of the two waves can generate pressure head variations of different frequencies and amplitudes. The frequency and shape of pressure histories are controlled via the delayed closure of one of the two valves. The interference phenomena in an ideal pipeline system are described with the aid of basic water hammer theoryPrispevek obravnava nov vodno udarni interferometer. V osnovi je to akustični cevni interferometer, ki je krmiljen z zapiranjem dveh ventilov. Naprava generira dva vodno udarna vala, ki medsebojno delujeta vzdolž s kapljevino napolnjene cevi. Superpozicija teh dveh valov lahko generira oscilacije tlačnih višin različnih frekvenc in amplitud. Frekvenca in oblika tlačnih valov sta krmiljeni s časovnim zamikom zapiranja enega od dveh ventilov. Interferenčni pojavi v idealnem cevnem sistemu so popisani s pomočjo osnovne teorije vodnega udaraTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
