고진공 슬러리 펌프 개발을 위한 수치해석적 연구

Slurry pumps have a wide range of industrial applications. However, as slurries contain abrasive and erosive solid particles, slurry pump components are subjected to severe wear and the pump system may even fail. Numerical simulations for developing a slurry pump model with 4 plate-type rotors were conducted using water as the pumping fluid. A commercial CFD package, STAR-CCD+, was used to simulate the flow characteristics depending on the atmospheric pressure through the inlet boundary. It is found that the simulation results are available in qualitatively studying the correlation of flow behaviors for a better pump design.
