Evaluation of Steam Explosion (ESE): premixing (original) (raw)

The steam explosion phenomenon is generally divided into four stages: premixing of melt and coolant, triggering of explosion, explosion escalation and propagation, expansion and work production. This contribution is assessing the first stage of steam explosion process while taking advantage of alternative approach, namely probabilistic multiphase flow equations. First, the equations and method of their solution are briefly discussed. Following the experiments "Billet 1000" (Oulmann and Hamon, 1994) the geometry was modelled using finite difference technique. The results for four phase mixture (melt, water, vapor, air) are presented in form of graphs depicting velocity, pressure, and phase presence probability fields. At the end, the conclusions and future plans are given aiming at better steam explosion understanding.
