【 摘 要 】

In the downstream process of an energy plant, a supersonic separator is a new technology that dehydrates natural gas with pressure and temperature differences using centrifugal force. Compared to other separating devices, a supersonic separator has the advantage of low cost in maintenance and its compatibility. In this study, the effect of the number of grooves on the swirling intensity of a supersonic separator was studied by numerical analysis using RNG turbulence model. Commercial CFD code ANSYS CFX 17.1 was used to determine and display a result of temperature and velocity distribution of the flow characteristics of a supersonic separator. Numerical results showed that the swirling intensity was proportional to the number of groove shapes but decreased when the number of grooves exceeded a certain number. As a result, a supersonic separator including the number of grooves with the highest swirling intensity deduced.
