초록

Vacuum pump transfers waste that is pulverized by integrated macerator. For this reason, unlike ordinary pump systems, there is a rotating macerator ahead of impeller for pulverizing. It is hard to predict numerical solution because area of Inlet flow path changes according to the rotation angle of the integrated macerator. So, in this study, the verification of performance evaluation method of Marine vacuum pump were numerically studied by commercial ANSYS CFX 13.0 software. We select a model of performance evaluation for study, and we analyze change of inlet flow path of integrated macerator according to rotation angle. We generate 5 model sets according to rotation angle of the integrated macerator. And we evaluate their performance by numerical analysis. Then, we analyze internal flow field and performance according to rotation angle of the integrated macerator based on numerical analysis result. In addition, we compared with experimental data for validity of numerical result by using steady state analysis.
