Y. Itaya et al., 3-DIMENSIONAL HEAT AND MOISTURE TRANSFER WITH VISCOELASTIC STRAIN-STRESS FORMATION IN COMPOSITE FOOD DURING DRYING, International journal of heat and mass transfer, 38(7), 1995, pp. 1173-1185
A simulation model was developed for three-dimensional heat and moistu
re transfer and viscoelastic hygrostress formation in a composite body
undergoing drying. In the model the chemical potential of moisture in
the body was used as a mass transfer potential since different materi
als had different affinities to moisture. The governing equations were
solved numerically by a finite element method. The model was validate
d experimentally through drying experiments using triply layered brick
shaped samples made of the hydrates of starch granules and of 3:1 mix
ture of starch granules and sucrose.
