Resumen:
The transient process of heat transfer between a high-temperature emulsion packet and an immersed surface is simulated using Computational Fluid Dynamics (CFD) tool in order to estimate the total heat transfer coefficient due to the emulsion phase, hD, and its radiant contribution, hrad,D. These coefficients are compared with experimental data (Ozkaynak et al., “Heat transfer in high temperature fluidized beds”, Lehigh University, 1981; Il´chenko et al., “Study of radiative heat transfer in fluidized bed”, J. of Eng. Phys., 14, 4, pp. 602-608, 1968) and with coefficients calculated from the Generalized Heterogeneous Model (Mazza et al., “Evaluation of overall heat transfer rates between bubbling fluidized beds and immersed surfaces”, Chem. Eng. Comm., 162, pp. 125-149, 1997). A good agreement is found with experimental data and the Generalized Heterogeneous Model revealing that the local simulation to quantify the heat transfer between the emulsion phase and an immersed surface may result convenient
