Premixing-related behavior of steam explosions

Abstract Three recently published premixing experiments, the Magico, mixa , and Faro , are discussed comparatively, and two of them, the Magico and Faro , are analyzed with the help of the computer code Pm-alpha . The results of these analyses are shown to provide quantitative interpretations of the data, and to suggest conditions/measurements in further experiments to enhance the insights thus obtained. Also, a quantitative radiography technique is described and applied to Magico for the measurement of chordal-averaged void fractions in the mixing zone. The results are in excellent agreement with Pm-Alpha predictions, thus confirming the previously reported good comparisons with the local (point) measurements of Flute .
