CFD-DEM simulations of a hot gas jet issuing into a pseudo 2D gas-solid fluidized bed of glass particles are reported. A novel CFD-DEM model accounting for fluid-particle heat transfer has been developed and used for this particular research. In this work the background gas is maintained at minimum fluidization velocity and room temperature (300 K) while a hot gas jet (500 K) is injected from the center of a pseudo 2D bed. Three different particle sizes have been studied (1 mm, 2 mm and 3 mm). The hot gas jet causes continuous bubble formation and propagation in the bed thus creating a circulation pattern of particles. Using the detailed simulation data various kinds of analysis are presented on the particle temperature statistics like standard deviation and distribution profiles of time-averaged particle density, volume flux and temperature variation about the mean. Further, a tracer particle analysis is presented that shows the variation of particle temperatures about the mean for different particle sizes. (C) 2015 Elsevier B.V. All rights reserved.
