Implication

Experimental analysis reveals reduced gas accumulation in two-phase flow using passive control steps, suggesting design improvements for centrifugal pumps.

Key Points

Gas accumulation was reduced significantly, particularly at higher water flow rates, improving system performance and efficiency.
The experimental setup involved various two-phase flow conditions with liquid Reynolds numbers ranging from 59,530 to 78,330.
Passive control using upstream cross-flow steps enhanced turbulence and bubble dispersion without increasing flow separation.
Findings support better computational models and offer design insights for centrifugal pumps to minimize gas buildup.
