DOI: 10.1117/1.oe.60.3.036107
Abstract: Abstract. We report a large-core radial-firing optical fiber tip comprised of conically shaped air-pocket, fabricated by deforming a hollow optical fiber fusion-spliced with the large-core optical fiber (LCF) (core/cladding diameters = 200 / 220 μm) using the arc-discharge method. The… read more here.

Mathematical Model of Air Pocket Evolution during Water Filling a Long-Slope Pipeline and Its Application to Air Removal Prediction
Sign Up to like & getrecommendations! Published in 2020 at "Mathematical Problems in Engineering"
DOI: 10.1155/2020/3157850
Abstract: During water filling a long-slope pipeline, air pocket is very likely to be entrapped at peak point. In order to track air movement and predict air removal conditions, a mathematical model of air pocket evolution,… read more here.
