Biomass gasification in a fluidized bed reactor is a complex process involving intricately
multi-scale and multi-physics processes and may be affected by many operating …

A general weighted space-time averaging procedure is developed and utilized to obtain the
average balance equations for granular materials. The method is applicable to both solid …

A model is presented for mathematically describing the thermofluid dynamics of dense,
reactive, gas–solid mixtures. The model distinguishes among multiple particle classes …

While slow granular flows have been an area of active research in recent years, heat
transfer in flowing particulate systems has received relatively little attention. We employ a …
