shrinkage and permeability. The converse is true for the other species where relatively higher isotropy has been encountered for the same parameters compared with C. citriodora. Again this is reflective of other wood properties measured for these species. The ratio of longitudinal diffusion to both radial and tangential directions is much greater for E. obliqua than C. citriodora, indicating E. obliqua’s greater propensity for drying in the longitudinal direction which may be advantageous during vacuum drying. Further work is planned to test this hypothesis by simulating drying in the longitudinal direction using Transpore 2-D. 150 150 100 100 L3 L2 L1 T3 T2 T1 R3 R2 R1 L3 L2 L1 T3 T2 T1 R3 R2 R1 50 00 5 10 15 20 25 Time (days) Figure 58.
