RU: Слошингом называется явление плескания жидкости под действием сил гравитации.
Проблема выплескивания жидкости из движущихся или стационарных контейнеров по-прежнему волнует умы инженеров аэрокосмической, гражданской и ядерной промышленностей, а также проектировщиков автоцистерн и судовых танкеров. Это объясняет наличие обширной экспериментальной базы по слошингу.
Команда расчётчиков провела сравнение эксперимента [1] с СFD-моделированием во FlowVision. Для расчёта выбрана постановка в системе координат бака, относительно которой задан гармонический закон изменения вектора гравитации.
ENG: Liquid sloshing effect occurs due to oscillations of the gravity vector. The problem of liquid sloshing in moving or stationary containers remains of great concern to aerospace, civil, and nuclear engineers and designers of road and ship explains the appearance of large experimental base for sloshing effects.
The engineers team has compared the experimental data [1] with cfd-simulation in FlowVision. For this case simulation was carried out in the tank coordinate system, relative to which the harmonic law of changing the gravity vector was set.
