Development of High Performance Steam Separator System (2) Performance test for Improved lower pressure losses separator

In order to verify the two-phase flow simulation method, 1/2.22 scale test section was used for high-pressure two-phase flow test. The pressure characteristics and the separating performance of the improved swirler designed by two-phase simulation method are also verified by 1/2.22 scale model experiment. It is found that the improved swirler can decrease pressure losses by about 59 percent compared to the conventional swirler and it can almost keep the same discharged water rate as the conventional swirler. We confirmed that the separator system with the selected swirler can decrease pressure losses more than 20 percent compared to the total pressure losses of the conventional separator without decreasing the discharged water rate by 1/2.22 scale-model experiment.
