The validity of a correlation model with a lumped parameter system (simple correlation model) was examined for the case of binder segregation during convective drying of slurry slab, which, in contrast with a prediction model by the distributed parameter system (accurate prediction model), was intended to provide rapid feedback of research results. A simple correlation model for binder segregation accompanied by drying shrinkage was proposed for convective drying of slurry slab by expansion of the authors' previous lumped parameter model in series without drying shrinkage. Experimental information about the formation of thin surface-layer rich in binder and the effect of adsorbed binder reported by others was considered in the proposed model. Results calculated with the proposed model from measured drying data showed satisfactory agreement with the authors' previous experimental results. The success of the proposed model in reproducing the experimental results obtained under limited conditions suggests the possibility of developing a generalized simple correlation model for binder segregation during convective drying of slurry slab.
