摘要：

This paper reports on experimental and analytical research in the field of forced-aeration windrow composting. The adequacy of a non-Darcy flow equation to describe flows through organic porous media is discussed. The windrow permeability and inertial parameter are determined and related with the substrate moisture and volatile solids contents. Another aspect studied is the transient variation of airflow characteristics and compost density. Comparisons between the analytical model and measurements are also made.
