摘要: Abstract In the bubbling regime of operation for fluidized beds, major mechanism heat transfer is transient conduction to periodic packets densely packed particles at surface. The well known Mickley and Fairbanks model, with various subsequently proposed modifications, adequately describes this mechanism. However, no adequate theory exists in high-temperature beds where radiative contribution becomes significant. Analysis complicated by nonlinear interaction radiation conduction/convection. This paper a differential formulation combined radiative/ conductive process. discrete flux method used Churchill et al. transport heterogeneous media applied here problem beds. Packets are modeled as radiatively participating absorption, scattering, emission radiati...
