ABSTRACT = {Combines theories of gas dynamics, fluid dynamics and numerical heat transfer theory, the condensing flow characteristics of water vapor in wet 
natural gas within the Laval nozzle were studied. A mathematical model was developed to predict the spontaneous condensing phenomenon in the 
supersonic flows using the classical nucleation and droplet growth theories. The numerical approach is validated with the experimental data by using 
UDF and UDS modules in FLUENT software, which shows a good agreement between them, and showed that the mathematical model can better 
predict the parameter changes in the condensation process. The condensation characteristics of water vapor in the Laval nozzle are described in 
detail. The results show that the condensation process was a rapid variation of the vapor-liquid phase change both in the space and in time, the 
distribution of nucleation rate is restricted to a small area. The spontaneous condensation of water vapor will not appear immediately when the steam 
reaches the saturation state. Instead, it occurs downstream the nozzle throat, where the steam is in the state of supersaturation. The previous 
accumulation of Supersaturation has led to a nuclear process occurring in a very short time. The degree of supercooling was also dramatically 
reduced in this small area, and when it is below the supersaturation limitation, the nucleation process ceases to occur.},
