Abstract
Fluid machineries for fluid food have been used in wide variety of field i.e. transportation, the filling, and improvement of the quality of fluid food. Although, flow conditions of it are quite complicated because fluid food is different from water. Therefore, the design method based on the internal flow conditions is not conducted. In this research, centrifugal pump for fluid food having semi-open impeller and small blade number was used to decrease shear loss and keep wide flow passage. In this paper, performances and internal flow conditions of pump having a general outlet blade angle 22.5 deg. using low viscous fluid were clarified by experimental and numerical analysis results.
