Abstract
Генератор коливань плинного середовища містить перепону, що займає більшу частину камери коливань. На фронтальній частині цієї перепони виконана виїмка, що обмивається струменем плинного середовища в процесі його коливань. Засоби для обмеження впливу нижньої течії плинного середовища на коливання струменя містять поздовжній елемент, що розміщений нижче за потоком задньої частини перепони та виключає проникнення потоків плинного середовища з одного проходу до другого.
