With regard to future calculations of the combustion inside a packed bed of wooden particles, the drying process of a single wet particle is simulated in the present study. Essentially, conservation equations in spherical coordinates are solved by a finite volume approach for the interior of the single wooden particle. It is shown that a thin transition zone between the wet and the dry area exists during evaporation. The fundamental reasons are pointed out. Furthermore, the high velocity values in the transition zone are explained physically. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
