Аннотация

A supersonic separator is state-of-the-art machinery that twists flow and induces temperature differences to separate impurities from natural gas. In order to improve the performance of a supersonic separator, thermal-flow fields should be thoroughly investigated. In this paper, the design optimization of a supersonic separator was performed using the commercial computational fluid dynamics (CFD) code, ANSYS CFX. The central composite design (CCD), one of the design of experiment (DOE) techniques, was employed to select the design points. Based on the results of the DOE, surrogate models were generated through the response surface method (RSM) to derive the optimal design with the best performance. The optimally designed model showed better swirling performance and consequential thermal effects than those of the reference model.
