Effect of a New Type of Adherent Axisymmetric Cyclone on Internal Flow Field Characteristics of Supersonic Separator

As a new technology, supersonic cyclone separation technology has achieved great success in natural gas exploitation and processing, which has the advantages that traditional gas-liquid separation devices do not have. Cyclone is used to realize gas-liquid separation and is closely related to separation performance of separator. In this paper, an adherent axisymmetric cyclone was used. This study based on FLUENT software, by changing the blade parameters, to simulate the flow field inside the separator. The effects of blade thickness and number on temperature and swirl intensity in separator were studied. The results show that the adherent axisymmetric cyclone can form a stable swirl field and has a small volume, which weakens the impact of shock waves to some extent. The increase of the number and thickness of blades causes the gas parameters to fluctuate violently and the shock wave moves upstream of the separator. Within a certain threshold, blade thickness almost does not affect the swirl intensity. When the critical value is exceeded, the swirl intensity increases with the decrease of the blade thickness. Since the number of blades is positively correlated with the swirl intensity, this trend causes the critical value to move back. Within the scope of this study, swirl intensity increases as blade number increases.
