Numerical Simulation on Condensing Flow of Water Vapor of Wet Natural Gas Inside the Nozzle

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… Show more

“…Liu et al (2015Liu et al ( , 2017 studied the variations of pressure and temperature in a Laval nozzle in high-speed compressible flow. Xiao et al (2017) pointed out that the temperature decreased when the wet natural gas flows through the Laval nozzle. Some researchers (Bian et al 2018b;Cao et al 2019a) proposed that under the same ratio of inlet pressure to outlet pressure, the temperature of the gas in a Laval nozzle drops significantly more than that of other throttling devices.…”
