Design of Inducer-Impeller Configurations of Self-Priming Vacuum Pump Using Response Surface Method

Self-priming vacuum pump is characterized for absorbing viscous fluid such as slurry and it is operated by the rotation of inducer and impeller generating partial vacuum in the rotor casing. In this study, the effect of inducer-impeller configurations on the performance of self-priming vacuum pump was precedently investigated with design parameters by using commercial code, ANSYS CFX to formulate the ranges of input parameters for optimization. And then, the optimization of inducer-impeller configurations was conducted by using response surface method (RSM) based on design of experiment (DOE) and the optimal model which provides the maximized head was suggested.
