Abstract
Flow behavior and heat transfer performance of gas and particles in a vertical tube are modeled by means of the combination of large eddy simulations for both gas and solid phase, and the kinetic theory of granular flow for particle collisions. The subgrid-scale viscosity model and subgrid-scale thermal conductivity model for gas phase and solid phase are based on the Smagorinsky form. The predicted average convective heat transfer coefficients are compared to experimental results measured by Depew et al., and show similar trends between simulations and experiments.
