Abstract:

In order to deeply understand the mechanism of the explosion of molten aluminum liquid in contact with water and quantify the damage influence caused by the explosion, data models and calculation analysis were established in terms of the overpressure damage caused by physical steam explosion and chemical oxidation reaction explosion and the flight distance of explosion fragments. The damage to personnel and buildings caused by the overpressure damage due to the explosion of molten aluminum liquid in contact with water under different calculated amounts was described in detail, and the influence range related to the flight distance of explosion fragments under different ejection angles was discussed, so as to more intuitively understand the damage influence caused by the explosion. The results show that the chemical explosion is the most destructive, followed by the physical explosion and the fragment ejection caused by the explosion during the explosion of molten aluminum in contact with water. At the same initial velocity of the ejection, the farthest horizontal distance of the fragment is achieved at the ejection angle of 30°.
