Experimental characterization of the dispersed bubbles in the slug of an air–water slug flow in a vertical pipe
Abstract Slug flow is one among the different flow patterns that two-phase flows can assume. This pattern is composed of a Taylor bubble and a liquid slug and can commonly occur in pipes in the oil and gas industry. Given the transient and intermittent behavior of this kind of flow, it becomes neces...

| 520 | |a Abstract Slug flow is one among the different flow patterns that two-phase flows can assume. This pattern is composed of a Taylor bubble and a liquid slug and can commonly occur in pipes in the oil and gas industry. Given the transient and intermittent behavior of this kind of flow, it becomes necessary to describe its characteristics. In this study, an experimental characterization of the dispersed small bubbles in the slug flow in a 0.026-m ID, 14-m-long vertical pipe was developed. Experiments for air and water were carried out, with both the gas and the liquid superficial velocities ranging from 0.2 to 1.5 m/s. The monitoring of the slug flow structures was accomplished by using a wire-mesh capacitive sensor. A high-speed camera was used to observe the nose shape of the Taylor bubbles and the dispersed small bubbles in the liquid slug. A phenomenological analysis of the flow was developed as a function of the dimensionless Froude and Reynolds numbers. The mean diameter and aspect ratio of the dispersed bubbles were calculated as a function of the liquid flow inertia, and a decrease in their sizes and deformation with the increase in the Reynolds number was observed. These small bubbles modify the nose shapes of the Taylor bubbles leading to flattened forms. Additionally, the transition from homogeneous to wall-peak bubble distributions was observed to be a function of the increase in the population of dispersed small bubbles. | ||

Abstract Slug flow is one among the different flow patterns that two-phase flows can assume. This pattern is composed of a Taylor bubble and a liquid slug and can commonly occur in pipes in the oil and gas industry. Given the transient and intermittent behavior of this kind of flow, it becomes necessary to describe its characteristics. In this study, an experimental characterization of the dispersed small bubbles in the slug flow in a 0.026-m ID, 14-m-long vertical pipe was developed. Experiments for air and water were carried out, with both the gas and the liquid superficial velocities ranging from 0.2 to 1.5 m/s. The monitoring of the slug flow structures was accomplished by using a wire-mesh capacitive sensor. A high-speed camera was used to observe the nose shape of the Taylor bubbles and the dispersed small bubbles in the liquid slug. A phenomenological analysis of the flow was developed as a function of the dimensionless Froude and Reynolds numbers. The mean diameter and aspect ratio of the dispersed bubbles were calculated as a function of the liquid flow inertia, and a decrease in their sizes and deformation with the increase in the Reynolds number was observed. These small bubbles modify the nose shapes of the Taylor bubbles leading to flattened forms. Additionally, the transition from homogeneous to wall-peak bubble distributions was observed to be a function of the increase in the population of dispersed small bubbles.

This pattern is composed of a Taylor bubble and a liquid slug and can commonly occur in pipes in the oil and gas industry. Given the transient and intermittent behavior of this kind of flow, it becomes necessary to describe its characteristics. In this study, an experimental characterization of the dispersed small bubbles in the slug flow in a 0.026-m ID, 14-m-long vertical pipe was developed. Experiments for air and water were carried out, with both the gas and the liquid superficial velocities ranging from 0.2 to 1.5 m/s. The monitoring of the slug flow structures was accomplished by using a wire-mesh capacitive sensor. A high-speed camera was used to observe the nose shape of the Taylor bubbles and the dispersed small bubbles in the liquid slug. A phenomenological analysis of the flow was developed as a function of the dimensionless Froude and Reynolds numbers. The mean diameter and aspect ratio of the dispersed bubbles were calculated as a function of the liquid flow inertia, and a decrease in their sizes and deformation with the increase in the Reynolds number was observed. These small bubbles modify the nose shapes of the Taylor bubbles leading to flattened forms. Additionally, the transition from homogeneous to wall-peak bubble distributions was observed to be a function of the increase in the population of dispersed small bubbles.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Slug flow</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Vertical flow</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dispersed bubbles</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Equivalent bubble diameter</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bubble aspect ratio</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gmyterco, Alexandre</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rodrigues, Carolina C.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mancilla, Ernesto</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">dos Santos, Eduardo N.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">da Silva, Marco J.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">da Fonseca Junior, Roberto</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Morales, Rigoberto E.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of the Brazilian Society of Mechanical Sciences and Engineering</subfield><subfield code="d">Berlin : Springer, 2003</subfield><subfield code="g">45(2023), 9 vom: 27.

Experimental characterization of the dispersed bubbles in the slug of an air–water slug flow in a vertical pipe |
| abstract |
Abstract Slug flow is one among the different flow patterns that two-phase flows can assume. This pattern is composed of a Taylor bubble and a liquid slug and can commonly occur in pipes in the oil and gas industry. Given the transient and intermittent behavior of this kind of flow, it becomes necessary to describe its characteristics. In this study, an experimental characterization of the dispersed small bubbles in the slug flow in a 0.026-m ID, 14-m-long vertical pipe was developed. Experiments for air and water were carried out, with both the gas and the liquid superficial velocities ranging from 0.2 to 1.5 m/s. The monitoring of the slug flow structures was accomplished by using a wire-mesh capacitive sensor. A high-speed camera was used to observe the nose shape of the Taylor bubbles and the dispersed small bubbles in the liquid slug. A phenomenological analysis of the flow was developed as a function of the dimensionless Froude and Reynolds numbers. The mean diameter and aspect ratio of the dispersed bubbles were calculated as a function of the liquid flow inertia, and a decrease in their sizes and deformation with the increase in the Reynolds number was observed. These small bubbles modify the nose shapes of the Taylor bubbles leading to flattened forms. Additionally, the transition from homogeneous to wall-peak bubble distributions was observed to be a function of the increase in the population of dispersed small bubbles. © The Author(s), under exclusive licence to The Brazilian Society of Mechanical Sciences and Engineering 2023.
