Исследование нелинейных эффектов при взаимодействии волн типа цунами с подводными барьерами

Abstract

Приведены результаты исследования нелинейных эффектов при взаимодействии длинных гравитационных волн типа цунами с подводными барьерами. В качестве математической модели использованы двумерные уравнения Навье – Стокса в приближении несжимаемой жидкости. Численные результаты получены методом конечных объемов с использованием открытого пакета OpenFOAM. Получены новые данные по исследованию эффективности тонкого и непроницаемого подводного барьера. Показано, что при значениях параметра нелинейности волны больше 0.1 подводный барьер оптимальной высоты гасит около 80 % энергии падающей волны.
