Abstract

Results are shown of an experimental study concerning the heat transfer in a fluidization bed (2–13 mm) of particles, with a cylindrical thermoprobe used for measurements. A predominance of the convective component in the heat-transfer coefficient has been confirmed in the case of coarse particles. Acriterial formula is proposed for calculating the coefficient of external heat transfer in a fluidization bed with the Archimedes number Ar=1.4·105−3.0·108.
