Numerical simulation of structural optimization within a supersonic cyclone separator

Abstract

Supersonic cyclone separation technology, as a new type of natural gas dewatering technology, utilizes the temperature drop generated by ultrahigh velocity fluid flow to condense the water vapor, thus accomplishing the goal of gas-liquid separation. At the input pressure of 8.48×104 Pa (G), the input temperature of 279.6 K, and the input water steam quality score of 5%, the flow fields and condensation characteristics were compared within the steeped, attached, five-curved three separator structures and the control group without the separator structure. The result shows that when the number of mahs of the ultrasonic spin separator of the ladder separator structure reached 1.51, the minimum pressure is −7.49×104 Pa, resulting in a temperature drop of approximately 100 K, and the flow field is most conducive to droplet condensation and growth; the maximum nucleation rate is 2.23×1023 kg−1·s−1, and the droplet diameter is 6.64×10−3μm.
