Moreover, very few parameterizations are reported on the wall- and fluid-granular material convective thermal heat transfer coefficients. For introductory studies, the work of Natarajan and Hunt [55], Gunn [25], Kuibe and Broughton [40], Kuipers et al [41] and Patil et al [59] might be consulted. To enable validation and reliable predictions of non-isothermal non-adiabatic reactive granular flows the thermal conductivity and the convective heat transfer coefficients have to be determined with sufficient accuracy. For certain processes this may be an important task for future research in the field of granular flows in fluidized beds.

Numerical simulations of granular flow and heat transfer in an agitated filler dryer are presented using TPD. The effects of operating parameters (wall tonperature and impeller speed) and batch size on drying behavior have been systematically stedied and compared with experimental data. Detailed analysis of temporal profiles of temperature and solvent content in the bed was performed. Under constant fill, both...
