Drying of Flat Plates

TABLE 14 Evaporative Drying of Cylindrical Green Body 

For flat plate geometry, the overall mass trasnfer flux,y (moles/area/ time), resulting from the total partial pressure profile over the boundary layer and across the pores is given by 

At steady state, both the mass transfer flux and the heat transfer flux are balanced according to 

With the equations in Table 14.4, all the possible rate controlling steps are established allowing the prediction of the total time, T at, to dry a green body, which is the sum of all the drying times for the green body, considering only one rate determining step at a time.
