The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

SINOPSIS

Gas-Liquid annular two-phase flow is one of the most common flow regimes in many industrial equipment. In this flow regime, liquid in part appears as a film on the channel walls whilst the rest of the liquid is carried as drops by the gas flowing in the center of the channel. Drop sizes and their velocities play a vital role in processes involving heat and mass transfer. This information is more useful for the oil industry where inclined drilling has become a common practice. The effect of inclination on the drop sizes and their velocities is still unknown and requires further investigation.
In this work, an inclinable two-phase flow rig has been developed and two laser techniques - Phase Doppler and Laser Diffraction - have been employed to investigate flow at various flow conditions. The Laser Diffraction system mounted on the rig gave drop size distributions in the flow channel as the column was rotated from the vertical to the horizontal position. The Phase Doppler system, on the other hand, was attached with the rig and was rotated along the flow column to give drop sizes and their velocities under the similar flow conditions. This paper compares the data obtained through these two techniques and also describes the limitations of each technique in making measurements under identical flow conditions. Problems in employing these two laser techniques are quite different and have been explained in a greater detail. In the end some typical results for both techniques have been presented and fully analyzed.
