Heat transfer processes in fluidized beds
Fluidized beds - Mass and heat transfer

Heat transfer in a gas-solid medium depends primarily on the thermophysical properties of the divided solid, but also on those of the interstitial gas.

• These, i.e. the gas's density ρ _g , its mass heat capacity C _{P g} , its thermal conductivity λ _g , and its dynamic viscosity µ _g , are all highly temperature-dependent.

  The mass heat capacity, thermal conductivity and dynamic viscosity of gases depend on their composition and are increasing functions...
