We are modeling the drying of tropical woods in this work. Experimental measures are made on sapelle (Entandrophragma Cylindricum) and lotofa (Sterculia Rhinopetala) coming from Cameroon forest. A part of thermophysical parameters used is experimental obtained on each wood species and another is taking in the literature. Numerical simulations results of the drying of our wood samples give a good description of experimental points. The present model can to be taken to explain the drying of the other tropical woods, but a determination of thermophysical parameters of each wood to dry is necessary.
