In this work, analytical solutions of the thin-layer and the Luikov models were proposed. For the thin-layer model, the moisture content and temperature distribution inside a biomass, assimilated to a parallelepiped material, are uniform whereas the Luikov model considers the sample as a porous medium. Analytical solutions of the Luikov model equations were obtained using Hermite’s zero-order approximation. These analytical solutions and those of the thin-layer model equations were applied to forced convection drying of two types of biomass: raw olive pomace (ROP) and deoiled olive pomace (DOP). It has been shown that the Luikov model is in good agreement with the experimental results except for the case where the sample has a thickness of 0.5 cm. In addition, thermal properties of ROP and DOP have been determined experimentally. On the other hand, a brief parametric study has been conducted and simultaneous effects of the dimensionless numbers: Luikov (Lu < <1), Kossovitch (Ko) and Posnov (Pn), on the drying process are highlighted. Thus, the increase of Luikov number accelerates the drying process and for specific couples (Lu and Ko) or (Lu and Pn), a remarkable change of dimensionless average water content with respect to dimensionless average temperature is observed, at the beginning of the drying process.

在这项工作中，提出了薄层和Luikov模型的解析解。对于薄层模型，与平行六面体材料同化的生物质中的水分含量和温度分布是均匀的，而Luikov模型将样品视为多孔介质。使用Hermite的零阶逼近获得Luikov模型方程的解析解。这些解析解和薄层模型方程式的解析解被用于两种生物质的强制对流干燥：生橄榄果渣（ROP）和脱油橄榄果渣（DOP）。结果表明，除了样品厚度为0.5 cm的情况外，Luikov模型与实验结果吻合良好。另外，已经通过实验确定了ROP和DOP的热性质。另一方面，Lu <1），Kossovitch（Ko）和Posnov（Pn），突出了干燥过程。因此，Luikov数的增加加速了干燥过程，对于特定的偶数（Lu和Ko）或（Lu和Pn），在干燥开始时，观察到无因次平均水含量相对于无因次平均温度的显着变化。处理。
