A Comparative Analysis of Conductance Probes and High-Speed Camera Measurements for Interfacial Behavior in Annular Air-Water Flow

Rivera, Yago; Bidon, Maxime; Muñoz-Cobo, J. L.; Berna, C.; Escrivá, A. (MDPI AG, 2023-10)

[EN] Different techniques are used to analyze annular flow, but the more interesting ones are those techniques that do not perturb the flow and provide enough resolution to clearly distinguish the interfacial phenomena ...
Characterization of the gas-liquid interfacial waves in vertical upward co-current annular flows

Cuadros-Orón, José Luis; Rivera-Durán, Yago; Berna, C.; Escrivá, A.; Muñoz-Cobo, J. L.; Monrós-Andreu, G.; Chiva, S. (Elsevier, 2019-05)

[EN] For more than fifty years, hundreds of research works have focused on the study of annular flow because of its huge importance in many industrial processes, for instance, chemical, petroleum, etc., being of particular ...
Comparison of Refractive Index Matching Techniques and PLIF40 Measurements in Annular Flow

Rivera, Yago; Bascou, Dorian; Blanco-Muelas, David; Álvarez-Piñeiro, Lucas; Berna, Cesar; Muñoz-Cobo, J. L.; Escrivá, A. (MDPI AG, 2023-04-05)

[EN] This paper investigates non-invasive techniques for annular two-phase flow analysis, focusing on liquid film characterization to understand the interfacial phenomena that are crucial for heat and mass transfer. Limited ...
Experimental and Modelling Study of Interfacial Phenomena in Annular Flow with Uncertainty Quantification

Rivera Durán, Yago (Universitat Politècnica de València, 2023-07-03)

[ES] El flujo anular es uno de los regímenes de flujo bifásico más importantes y se caracteriza por que una fracción de líquido muy pequeña conocida como película de líquido que viaja cerca de la pared y un núcleo gaseoso. ...
Experimental study of the effects produced by the changes of the liquid and gas superficial velocities and the surface tension on the interfacial waves and the film thickness in annular concurrent upward vertical flows

Rivera-Durán, Yago; Muñoz-Cobo, J. L.; Cuadros, Jose-Luis; Berna, C.; Alberto Escrivá (Elsevier, 2021-01-01)

[EN] In this paper, we have performed an experimental study of the effect of changing the surface tension of the water in vertical annular concurrent two-phase flow (air + liquid) by adding small amounts of 1-butanol to ...
Review of droplet entrainment in annular flow: Characterization of the entrained droplets

Berna Escriche, César; Escrivá Castells, Facundo Alberto; Muñoz-Cobo González, José Luís; Herranz, L.E. (Elsevier, 2015-03)

[EN] Annular flow is characterized by a thin liquid film flowing on the pipe wall and a high velocity gas core flowing in its center, which normally carries liquid droplets. This review presents and analyzes most of the ...
Review of droplet entrainment in annular flow: Interfacial waves and onset of entrainment

Berna Escriche, César; Escrivá Castells, Facundo Alberto; Muñoz-Cobo González, José Luís; Herranz, L.E. (Elsevier, 2014-07)

[EN] Annular two-phase flow has been vastly investigated because of its large and deep involvement in industrial processes, particularly in nuclear engineering. This paper reviews most of the recent literature on the matter, ...
