A semi-empirical model is used to calculate the averaged surface void fraction in fluidized beds, εw, starting from experimental data on surface-to-bed heat transfer coefficient. The model is able to describe the effect of the main process parameters and shows that εw increases with minimum fluidization void fraction and particle Archimedes number.

Abstract
A semi-empirical model is used to calculate the averaged surface void fraction in fluidized beds, εw, starting from experimental data on surface-to-bed heat transfer coefficient. The model is able to describe the effect of the main process parameters and shows that εw increases with minimum fluidization void fraction and particle Archimedes number.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
