Влияние параметров источников импульсного давления на волновые поля в металлическом расплаве

Abstract

Based on mathematical modeling, the influence of the magnetic-pulse, the electric-discharge and the combined sources of the pulsed pressure on wave fields in aluminum melt was studied. An increase in the intensity of the wave fields in the melt with an increase in the amplitude, the pulsation period and the attenuation time of pressure pulsations created by pulsed sources was observed. The occurrence of cavitation in the melt under the action of the considered sources of pressure pulses was determined. A significant influence of the parameters of pulsed pressure sources on the change in the density of the internal energy of the melt was noted.

На основе математического моделирования выполнено исследование влияния параметров магнитно-импульсного, электроразрывного и комбинированного источников импульсного давления на волновые поля в расплаве алюминия. Отмечено повышение интенсивности волновых полей в расплаве при увеличении амплитуды, периода пульсации и времени затухания пульсаций давления, создаваемого импульсными источниками. Определено возникновение кавитации в расплаве под действием рассмотренных источников импульсов давления. Выявлено существенное влияние параметров импульсных источников давления на изменение плотности внутренней энергии расплава.
