Polydispersity is a challenging feature of many industrial and environmental multiphase flows, influencing all related transfer and transport processes. Besides their size, the fluid or solid particles may be distributed with respect to other propert

In CFD simulation of CFB combustion, computation of the local instantaneous conversion rate of a single fuel particle should be fast. Since fuel conversion is limited by mass and heat transfer and the rates of chemical reactions inside the particle,
