Advanced instrumentation for slug flow measurement, namely ECT, under laboratory conditions, is used on a horizontal pipe
In this study, oil with viscosity five times higher than water is used, as it is more relevant to industry
Comparison with void fraction in the liquid slug and slug frequency data available in literature shows similar trends.
Use of plots of average slug frequency against axial distance, probability density function (PDF) of void fraction and comparison of slug front and slug tail to establish flow development.
