摘要：

The critical mass flow rates were calculated for a wide variety of substances, including propane, ethylene, ammonia, chlorine, vinyl chloride, water and refrigerants. The mass flow calculations were based on isentropic homogeneous flow in thermal equilibrium and on newly generated thermodynamic data derived from appropriate equations of state such as the Benedict-Webb- Rubin equation, Starling's equation and the Martin-Hou equation. A generalized equation was developed to express the critical mass flux in a simple algebraic expression as a function of temperature, pressure and molecular weight. This universal two-phase flow prediction equation gave good results on all substances tested. © 1990.
