... the characteristics of bubble flow in pump and shed new lights on the understanding of the performance of centrifugal pumps under two-phase flow conditions. gas–liquid two-phase flow bubble flow centrifugal pump CFD–PBM The centrifugal pump is widely used in petroleum, chemical industry, nuclear power...

... between operating parameters and pump performance, a further understanding via direct observation of the gas–liquid mixture was so far not possible. In this paper, we demonstrate the capability of ultrafast X-ray computed tomography (UFXCT) to disclose gas–liquid two-phase flow dynamics in the impeller...
