Численное моделирование вихревых пульсаций в гасителе шума трубопровода

Кирилл Андреевич Романов, Георгий Михайлович Макарьянц

Аннотация


В работе представлено исследование динамических характеристик гасителя колебаний в трубопроводе, а именно исследование вихревых пульсаций в трубопроводе, возникающих за гасителем колебаний. Для этой цели была разработана численная методика оценки гидродинамического шума, которая основана на модели турбулентности LES. Полученные данные численных расчётов показывают характерный уровень гидродинамического шума в гасителе колебаний, который позволяет оценить уровень фонового шума в трубопроводе. Данные, полученные в результате численных расчётов, частично совпадают с экспериментальными данными, которые подтверждают адекватность разработанной модели в низкочастотном диапазоне.
