Abstract
In this study, the effect of two-phase interfaces on the resistance pressure in micro-capillaries has been first investigated experimentally. A new correlation was then proposed to predict the resistant pressure drop of two-phase flows in micro-channels. A particular point was observed in the measured resistant-pressure profiles, which cannot be explained by current theory. When the two-phase interface passes through this point, the resistant pressure suddenly increased at a constant rate. When a single fluid phase pass through this point, the resistant pressure does not change. Stimulated resistant pressure shows a good agreement with the measured results either before or after the particular point (within ±20% deviation), but cannot match the measured entire pressure profile. Simulation cannot explain the particular point where the resistant pressure profile suddenly changed.
