Distributions of pressure, velocity, and void fraction for one-dimensional gas-liquid bubbly flow in horizontal pipes / Phu D. Tran in Transactions of the ASME . Journal of fluids engineering, Vol. 130 N° 9 (Septembre 2008)  

Public ISBD [article]  inTransactions of the ASME . Journal of fluids engineering > Vol. 130 N° 9 (Septembre 2008) . - 9 p. Titre : Distributions of pressure, velocity, and void fraction for one-dimensional gas-liquid bubbly flow in horizontal pipes Type de document : texte imprimé Auteurs : Phu D. Tran, Auteur Année de publication : 2009 Article en page(s) : 9 p. Note générale : Fluids engineering Langues : Anglais (eng) Mots-clés : one-dimensional gas-liquid bubbly flow  horizontal pipes Résumé : A homogeneous model for prediction of the longitudinal distributions of pressure, velocity, and void fraction for two-phase bubbly flow in horizontal pipes is presented. The mixture flow is described by a system of two nondimensional ordinary differential equations that can be integrated numerically to yield the distributions of the flow variables along the pipe. The viscosity of the two-phase mixture is assumed to vary with the void fraction according to a polynomial form. Experimental data were obtained for a range of air-water bubbly flow in a horizontal pipe. Prediction of pressure distributions along the pipe compares favorably with experimental data, while prediction of void fraction distributions can be achieved with moderate accuracy.
