• Effect of Dissolved Non-condensible Gas on Vapor Explosion

抄録

In order to investigate the triggering mechanism of vapor explosion, experiments were carried out in the system of a carbonate water droplet impinging onto a molten lead-bismuth pool. Carbon dioxide dissolved into water had a suppression effect on vapor explosion. The non-condensible gas reduced condensation rate, which resulted in restraining a water micro jet from impinging on to the molten lead-bismuth surface to induce the fine mixing after the bubbles had expanded excessively and had contacted the subcooled water.
