Abstract
Oil-Hydraulic pump consisting of swing twin-cylinder becomes to be used as a next generation of low vacuum pump. However, there is no enough flow-analysis for design improvement. It is essential to develope a numerical method for flow-analysis before manufacturing, in economic sense. Using a commercial code (Fluent), developed for flow-analysis, useful informations for design of pump were provided. Two-dimensional analysis has been performed to investigate the flow parameters such as pressure and velocity distributions between the swing twin-cylinder and the fixed cylinder. This numerical method will be used to design a better performance of pump consisting of swing twin-cylinder.
