“…There was deviation in theoretical and experimental results of wood average moisture content ranges from À 12% to þ14% and the deviation of wood average temperature ranges from À 0.5% to þ 3%. The results of steady state and transient conditions were in good agreement with experimental and theoretical works and simulation model verified that it can be an effective tool for the design of a solar timber dryer and the prediction of moisture content behavior [24].…”

“…Timber has been suggested by many researchers [1,2] to continue as a primary raw material for many products, in building construction and in the furniture industry. Due to the possession of attractive characteristics, such as its low embodied energy, its low carbon impact, its sustainability, and being a renewable resource, Falk [2] mentioned that wood is expected to uphold its demand for future building construction.…”

A numerical simulation for the modeling of solar kilns for hardwood timber drying with different boundary conditions has been developed in this work. This simulation has been used to predict the key behavior of the wood and the kiln itself under different geographical and weather conditions in Australia. This work, therefore, enables a site to be suggested that is likely to give the best kiln performance both in terms of the productivity and the quality of the end-use product. As test cases, realistic climatic conditions for three representative geographical locations in Australia, including Sydney (latitude 33.86 S), Melbourne (37.81 S), and Brisbane (27.46 S), have been considered in this simulation. Out of the three sites considered in this work, the fastest drying rates (and highest diffusion coefficients) were predicted in Brisbane. The highest level of instantaneous strain in the timber for this location was also predicted to be 0.0075 m/m, which is much less than the failure value (0.02 m/m). The moisture content distribution profile within the boards toward the end of the drying period was found to be almost uniform, which is likely to cause low degrade in the dried timber.

“…Drying is fundamentally a problem of simultaneous heat and mass transfer under transient conditions resulting in a system of coupled non-linear partial differential equations. The simulation of wood drying has been the subject of numerous works, including physical and mechanical formulations and numerical solutions [8][9][10][11].…”
