Na2CO3 - NaOH 혼합용융염과 물의 접촉에 의한 증기폭발에 관한 연구 = A Study on Vapour Explosion Caused by the Contact Between Molten Salt of Na2CO3 - NaOH Mixture and water

다국어 초록 (Multilingual Abstract)

Molten salt-water explosion caused by the contact between molten salt and water is one of vapour explosions.
An experimental study of the vapour explosion, which occurs when the molten mixture of Na₂ CO₃-NaOH and water come in contact was performed.
The pressure wave generated in each composition of molten mixtures was measured.
The results obtained are as follows;
1) The vapour explosian didn't occur for a molten salt of 100%- Na₂CO₃.
2) For a molten salt of Na₂CO₃80%-NaOH 20% mixture, a small vapour explosion occured initially, and a large vapour explosion, which showed the largest pressure wave among the present experiments, occurred after an induced period.
3) For molten salt of Na₂CO₃60%-NaOH 40% mixture and Na₂CO₃, 40%- NaOH-60% mixture, the vapour explosion occurred near the water surface shortly after they come incontact with water.
This explosion would be caused by fragmentation of the molten salts due to impulse generated when the molten salts and water come in contact.
