Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This work presents experimental studies on flow pattern and pressure drop of high-viscosity-ratio oil-water two-phase flow (oil-to-water viscosity ratio of about 1680:1 at 20°C). The test pipelines, the diameter of which is 50 mm, are made of transparent Perspex pipes to enable the visual observation of the oil-water flow pattern and the length of inclined pipes is 4.5 m. The oil-water two-phase flow pattern and pressure drop graphs were obtained from experimental data. The results indicate that the flow pattern of high-viscosity-ratio oil-water flow in inclined pipes presents different flow characteristics comparing with the low-viscosity-ratio oil-water flow, especially when the inlet water flux is low, a new flow pattern described as oil film at the pipe wall and inner dispersion of oil in water was observed; the oil-water pressure drops increase with increasing the inlet oil fraction, and in those high inlet oil fraction area the pressure drops appears a peak-valley relationship.
