000014087 520__ $$2eng$$aThe modeling of multiphase flows with a constant heat flux boundary is of great practical and fundamental significance. Assessing the feasibility of a unit operation often requires the prediction of wall temperature gradients, which can induce mechanical failure if they become too large. A numerical technique for modeling such a boundary condition (BC) is proposed for gas-solids flows, and directly applied within a computational fluid dynamics and discrete element method (CFD-DEM) software. This same technique can be extended to polydisperse systems and the two-fluid model. Computational Methodology All simulations were performed via MFIX, an open-source software developed by the U. S. National Energy Technology Laboratory for multiphase flows. Specifically, the hydrodynamics and heat transfer of a gas and monodisperse solids were modeled with the CFD-DEM framework within MFIX. The governing equations pertinent to heat transfer are outlined below for both phases. The gas phase is treated as a continuum via the following thermal energy balance [1]:
