✦ Synopsis

A theorettcal model to descnbe the heat transfer between an Immersed heater and unrestramed packed or quiescent fluldlzed bed IS presented The bed was drvided mto two regions of constant bed voldage and gas velocity (I) A region of Increased voidage close to the heat transfer surface (u) The area outside this Heat transfer was assumed to take place by steady state conduction and effective conductivmes were used to charactenze the heat transfer in both reaons The predictions of the model agreed with the expenmentally measured packed and quiescent bed heat transfer coefficients to w&n 25%
