Аннотация

Рассмотрена модель распределения тока при нагреве поверхности вольфрамового образца при импульсном воздействии электронным пучком. Модель основана на решении уравнений электродинамики и двухфазной задачи Стефана для расчёта температуры в области образца в цилиндрической системе координат. Параметры модели взяты из экспериментов на стенде Beam of Electrons for materials Test Applications (BETA), созданного в ИЯФ СО РАН. Рассмотрен частный случай аксиальной симметрии без учёта электродвижущих сил. Ток рассматривается как возможный источник вращения вещества, который наблюдается в эксперименте. Получены расчётные значения тока и ускорение вещества при температуре поверхности свыше 6000 К. Результаты проведённого моделирования показывают, что для получения ускорения, способного инициировать наблюдаемое в эксперименте вращение расплава, нужно учесть альтернативные механизмы создания тока в системе с учётом испарений вольфрама над пластинкой.
