摘要

Vortex pilot gas heater (VPGH) is an application of vortex tube in natural gas transmission and distribution regulation system. By closing the hot end of vortex tube and installing vortex heater on the outer layer to form a pilot gas self‐heating device, the pilot gas and vacuum nozzle can be heated to prevent freezing blockage caused by Joule‐Thomson effect. In this paper, the numerical simulation method of CFD software is used to simulate its internal flow field based on the standard k‐epsilon model, and the influence law of different inlet working parameters on its working performance is analyzed by controlling a single variable.
