| contents | CFD modeling of Air-Water Two-phase Annular Flow before a 90° elbow Andrés Felipe Melo Zambrano Nicolas Ratkovich Ingeniería CFD Two Water Phase Flow Air System In this work, a Computational Fluid Dynamics model is presented for the analysis of annular air-water flow before a 90° bend with a radius to diameter ratio (r/D) of 1.5, implementing the Volume of Fluid (VOF) model in STARCCM+ v9.2. An 8m-long vertical tube with an internal diameter of 0.076 m was studied for ten different air and water superficial velocities. The mean void fraction was compared between the experimental measurements, the CFD model, and a model in OLGA. The CFD and OLGA model presented an average relative error of 8.79 % and 17.05 %, respectively. 2015 artículo científico 0121-4993 https://www.redalyc.org/articulo.oa?id=121044223003 en http://www.redalyc.org/revista.oa?id=1210 Revista de Ingeniería application/pdf Universidad de los Andes Revista de Ingeniería (Colombia) Num.43 |
