PATINO, Luis y FIGUEROA, Rosmely. CONVECCIÓN DE CALOR EN EL FLUJO DE FLUIDOS A TRAVÉS DE UN LECHO DE EMPAQUE DE BAUXITA ACTIVADA. Rev. Fac. Ing. - Univ. Tarapacá [online]. 2004, vol.12, n.2, pp.27-34. ISSN 0718-1337. http://dx.doi.org/10.4067/S0718-13372004000200005.
A theoretic-experimental methodology is presented to determine the interstitial heat transfer coefficients in the water flow through packed bed of activated Bauxite, where the fluid is not in heat balance with the solid phase. The heat transfer coefficients are obtained through "Single Blow Transient Method" combining the experimental results obtained in a test set-up with the numerical solutions of the mathematical model. The system of partial differential equations generated in the mathematical model is solved through a numerical procedure based on the finite volumes method. Experimental test results and numerical solutions were obtained for different values of superficial speed of the fluid from the entrance of the bed and for different porosity values, obtaining themselves that the Nusselt numbers depend in great scale on the Reynolds numbers and the porosity of media
