Abstract
A fuel pump for a turbopump system has been designed under an international co-work program. The liquid methane fuel pump has an inducer, in front of centrifugal impeller blades, to improve cavitation performance. The three dimensional viscous flow in the fuel pump was investigated through numerical computation. An arrangement of the inducer and impeller has yielded a strong interaction between inducer and impeller blades. The performance of the pump was evaluated from the calculated results. A parametric study was performed for various design variables, and it could oner a database for design parameters to design a fuel pump. A modified design of a fuel pump was proposed by KIMM to improve pump performance.
