В работе рассматривается численное моделирование движения ледяного киля в двухслойной жидкости. Для описания нестационарной геометрии области на прямоугольных сетках используется метод погруженной границы. Приводятся результаты расчета силы сопротивления для различных значений чисел Фруда в сравнении с данными лабораторных экспериментов.

This paper considers numerical simulation of a moving ice keel in a two-layer fluid. The immersed boundary method is used for modeling of the non-stationary complex geometry on the rectangular grids. The results of the drag force computations for various Froude numbers are presented in comparison with the laboratory experiments.
