Two-Phase jet dispersion

摘要

This paper presents the state-of-the-art in the field of hazardous dispersion with special attention to two-phase jet conditions. After recalling the specificity of two-phase jet dispersion, the uncertain features of the integral and multidimensional models are discussed and specific suggestions for improvement are proposed. The boundary conditions corresponding to the rapid flow change just downstream of the orifice due to flashing, gas expansion and droplet formation are also considered. The lack of adequate two-phase jet dispersion data and the resulting poor validation of the models are particularly pointed out.
