Abstract

The convective heat-transfer coefficient α is one of the important parameters in the design of an indirect rotary dryer. A model that correlates α with several process parameters for an indirect rotary dryer without flights has been developed through dimensional analysis. According to the model, α increases with the product of the drum diameter D and rotation speed n, the moisture content x1, the tap density of the mixture ρbtand the virtual viscosity η; α decreases with the qualitative length of the dryer δ and the specific heat of the mixture λ.
