The mixing of particle clouds plunging into water Original Research Article

This work addresses certain fundamental aspects of the premixing phase of steam explosions. At issue are the multifield interaction aspects under highly transient, multidimensional conditions and in the presence of strong phase changes. They are addressed in an experiment (the MAGICO-2000) involving well-characterized particle clouds mixing with water and detailed measurements on both external and internal characteristics of the mixing zone. Both cold and hot (up to 1500°C) particle clouds are considered in conjunction with saturated and subcooled water pools. The PM-ALPHA code is used as an aid in interpreting the experimental results and the exercise reveals good predictive capabilities for it.
