Lumped parameter modelling and an introduction to optimization of one- dimensional nonadiabatic drying systems (Q761196)

A lumped parameter model, solved numerically, is proposed for drying in several one-dimensional systems. The model appears to be an advanced extension of the standard drying description based on the drying coefficient. This extension takes into consideration the solid enthalpy changes, partial transfer resistances of heat and mass in gas and solid phases and variation of all interface parameters. Optimization models of several dryers (cocurrent, countercurrent and crosscurrent type) are derived on the basis of kinetic and balance equations.
