Descripción
The transient process of heat transfer between a high-temperature emulsion packet  and the wall of an immersed surface is simulated using computational fluid dynamics  (CFD). From these simulations, the total heat transfer coefficient and its radiant contribution  due to the emulsion (dense) phase are evaluated. The results are compared  with experimental data (Ozkaynak et al.,  An experimental investigation of radiant  heat transfer in high temperature fluidized beds, in Fluidization IV, 1983, 371 - 378)  and with predicted values from the generalized heterogeneous model (GHM), (Mazza  et al., Evaluation of overall heat transfer rates between bubbling fluidized beds and  immersed surfaces,  Chem Eng Commun., 1997;162:125-149). The CFD simulations  are in good agreement with both, experimental data and theoretical GHM predictions  and provide a reliable way to quantify the studied heat transfer process. Also, the  GHM is validated as a practical tool to this end.
