Resumen
This work deals with experimental and numerical studies of a 3-D transient free-surface two-phase flow in a bench-scale channel flow. The aim was to determine how well the homogeneous model can predict the fluid dynamics behavior and to validate the model. The model was validated with experimental data acquired for two hydrodynamic situations. The mathematical model was based on the mass conservation equations for liquid and gas phases and on the momentum conservation equation for the mixture, assuming interpenetrating, continuum and homogeneous hypotheses. Turbulence has been considered for the mixture through the standard k-e model. The numerical methods were the finite volume method with pressure-velocity coupling and a numerical grid on a generalized Cartesian coordinate system. Good qualitative and quantitative agreements were found for both cases, making the prediction of the fluid dynamics behavior quite robust. 30 2 323 335 Arastoopour, H., (1978) Hydrodynamic Analysis Of Solids Transport, , Ph.D. Thesis, Illinois Institute of Technology, Illinois, Chicago Alizadehdakhel, A., Rahimi, M., Sanjari, J., Alsairafi, A.A., Cfd and artificial neural network modeling of two-phase flow pressure drop (2009) International Communications In Heat And Mass Transfer, 36 (8), pp. 850-856 Jovanović, R., Cvetinović, D., Stefanović, P., Swiatkowski, B., Turbulent two-phase flow modeling of air-coal mixture channels with single blade turbulators (2008) FME Transactions, 36, pp. 67-74 Gunzburger, M.D., Nicolaides, R.A., (1993) Incompressible Computational Fluid Dynamics: Trends And Advances, , Cambridge University Press, Cambridge Hansen, K.G., Madsen, J., Trinh, C.M., Ibsen, C.H., Solberg, T., Hjertager, B.H.A., (2002) Computational and Experimental Study of the Internal Flow in a Scaled Pressure-Swirl Atomizer, , ILASS-Europe, Zaragoza Kakaç, S., Venkataraman, M.R., Pramuanjaroenkij, A., Kotcioglu, I., Modeling of two-phase flow instabilities in convective in-tube boiling horizontal systems (2009) J. of Thermal Science and Technology, 29 (1), pp. 107-116 Launder, B.E., Spalding, D.B., The numerical computation of turbulent flows (1974) Comp.
