内容記述 | Investigation on the reduction of rotor-stator interaction in turbopump impeller/diffuser by using inverse design was presented. To reduce the rotor-stator interaction, modified impeller and diffuser were designed by 3D inverse design method. The unsteady pressure fluctuations in the impeller and diffuser were evaluated by unsteady CFD (Computational Fluid Dynamics) technique. The results of CFD show the rotating pressure pattern, and also the mechanism of the interaction between the impeller outlet and the diffuser inlet. The modified stage consisted of the impeller with staking and the diffuser with inlet sweep have the effect to reduce the rotor-stator interaction caused by lengthening the blade passing time. The pressure fluctuations of modified impeller/diffuser system decreases 20-30 percent less than those of original impeller/diffuser system without the staking and the inlet sweep. | |||||
