| Abstract: | After treating of the interphase heat, mass and momentum transfer rates of vapour-liquid two-phase flow, this paper describes a simplified mathematics model of the critical mass flow per unit area in the vapour-liquid two-phase flow nozzle. According to approximate assumptions based on the experimental results obtained by other researchers a mathematical expression of critical pressure ratio of vapour-liquid two-phase flow in nozzle is put forword. |
