Experimental studying of vapor explosion triggering during the breakup of a molten salt jet

The paper presents an experimental study using high-speed video recording of the process of vapor explosion on a breakup jet of molten NaCl salt in water. The regimes of jet breakup into large parts, accompanied by the separation of small satellite droplets, have been studied. For the first time, the propagation of a vapor explosion on two large fragments of jet breakup due to spontaneous triggering of the process on a droplet-satellite was reproduced and recorded under laboratory conditions. The possibility of a vapor explosion occurring at the initial stage of the first stage of coarse crushing and mixing of the melt jet is shown.
