A Moving Boundary Model for Isothermal Drying and Shrinkage of Chayote Discoid Samples: Comparison between the Fully Analytical and the Shortcut Numerical Approaches

Figure 4

Comparison between experimental data for vs. for chayote discoid samples and the 1-d moving boundary model predictions obtained with the two different models for shown in Figure 5(b). The red dotted curve shows model prediction with the α function adopting the linear approximation (equation (13)). The blue curve shows model predictions with the α function adopting the nonlinear approximation equations (28) and (29). The thickness calibration curve adopted is (equation (16)) and .
